How2 dial into GPRS using blueZ+dialup applet?

I got stuck with setting up a dial-up connection thru GPRS on my SonyEricsson Z600...

Dialup over GSM and GPRS from my laptop works fine:
* dial-up over a normal GSM line works from the Z, using BlueZ and the dialup applet from http://my-zaurus.narod.ru/bluetooth.html -so apparantly the Z and the phone are paired and the dialup applet does it job fine.
* dial-up over a GSM line AND GPRS both work fine from my Win2k laptop, using the same blue monkey bluetooth CF card which I use for the Z -so also the phone appears to be OK.

But if I try to dial-in from my Z using the settings below then the CF card LED flashes one or two seconds, the phone shows a BT link but no GPRS connection icon and the Z shows "initializing modem" forever until the connection is aborted after about one and a half minute.

The dialup applet settings for the GPRS connection for my provider (Orange Netherlands) I took from various sources -and again, these same settings work fine if I dial up from my PC:
* account: username and password are set to "orange" (actually I believe an arbitrary string would be OK), phone number to dial: *99***1#
* modem, BT device: /dev/rfcomm0, init string: AT+cgdcont=1,"IP","internet", speed: 57600, hardware flow control 6 secs
* network: all set to auto-detect
These settings match a data account CID=1, APN address "internet" on my phone.

What might be the problem here /what did I overlook?

Thanks for any suggestion...

Hard reset does not work

OK, I want to reset my Z to factory settings because of lots of problems which I cannot solve (eg: the USB cradle connection is gone, the CF card is lost during a few seconds after each suspend, my new SD card does not mount etc etc) -but now the hard reset does not work either!
After pressing the reset button in the battery compartment the Z reboots all right but everyting is still in place afterwards: time and installed applications, but also all problems.

Is there another way to restore the Z to factory settings? Eg, what does this "format" option in the maintenance menu do, would it help to use that?

REC - ipkg error, Segmentation fault

OK, fortunately I was able to retrieve the thread from my browser's cache

The problem I got stuck with is that the package command manager raises a very helpful error "ipkg says something went wrong, sorry" while installing the Affix application, to run bluetooth on my SL-5600 with a BlueMonkey CF bluetooth card. This happens while installing the first file of the Affix package: bluetooth-affix-kernel_2.0.2-3_arm.ipk.

The problem persists when I use another version of the ipk (eg, tried version 1.2.4 from affix.sourceforge.net/feeds/stable/zaurus/). Also, when I login as su and run ipkg install then following 2 messages appear:
Unpacking bluetooth-affix-kernel...Done.
Configuring bluetooth-affix-kernel...Segmentation fault

Lardman suggested that the problem might be in the 'postinst' file. Using his suggestions I was able to extract it from bluetooth-affix-kernel_2.0.2-3_arm.ipk, its contents are:

chown root /lib/modules/2.4.6-rmk1-np2-embedix/kernel/drivers/affix/*
chown root /lib/modules/2.4.6-rmk1-np2-embedix/kernel/net/affix/*

mknod -m 0644 /dev/bty8 c 60 8
mknod -m 0644 /dev/bty9 c 60 9
depmod -a

I checked my Z: all mentioned folders exist. Also I noticed that all files in data.tar.gz have been installed on the Z. Also I found elsewhere in /lib/modules/ similar files which apparantly remained from an the attempt to install Affix version 1.2.4, and an earlier attempt to install BlueZ.
I do not know what the various commands in 'postinst' do, however.

Is there anything in this 'postinst' file which might explain the 'Segmentation fault' which occurs while configuring 'bluetooth-affix-kernel'??

how 2 backup data stored on CF?

Does anyone know how to backup data from CF (or SD) to PC, using the backup/restore application for windows which comes with the SL5600?
This tool apparantly backs up only files under /home on the internal flash, but nothing which is stored on the CF.

Any suggestion is much appreciated.
