Almost Have Full Usb Networking With 5500

I am running Gentoo Linux on my laptop.
I have an SL-5500 sitting in the cradle.
I have usbnet working and I can ping from the SL-5500 to my laptop. I can also ping from my laptop to the SL-5500.
I am able to ssh from my laptop into the SL-5500.

Here is the network setup on my laptop as it relates to usb0:
My ifconfig line in /etc/conf.d/net looks like this: ifconfig_usb0=("192.168.129.1 broadcast 192.168.129.255 netmask 255.255.255.0 pointopoint 192.168.129.201")

FWIW, I have tried it both with and without the "pointopoint" directive and my results are the same.

Here is the network setup on the SL-5500:
- ip address: 192.168.129.201
- subnet mask: 255.255.255.0
- gateway: blank
- DNS (both blank)

From the Zaurus, I have no visibility of the internet. If I ssh into the Zaurus from my laptop and attempt a wget to my web site:

wget http://www.boyken.org
wget: www.boyken.org: Host name lookup failure

If I attempt the same thing via ip address, I get this:

wget http://69.72.158.138
Connecting to 69.72.158.138[69.72.158.138]:80
wget: Unable to connect to remote host (69.72.158.138): Network is unreachable

I feel like I am really, really close to getting this set up properly. Any help would be greatly appreciated!

Which Zimage Should I Use For My Sl-5500?

Yesterday I was given (yes, given) a fully-functional SL-5500. It is currently running the Sharp software which was upgraded to the 3.10 ROM. I would like to run OpenZaurus and OPIE. Here is my hardware configuration and I am looking for guidance as to specifically which zImage I should use.

My unit is an SL-5500
It appears to have 32MB internal memory
It has a 16MB CF card
I have a 512MB SD card I intend to use with it.

Last night I tried a couple of different zImage files (carefully following the instructions). I have a CF card reader that I used to copy the files and I made certain they were in the root directory. I attempted to flash several times (who came up with that crazy C+D+reset combo?) and I always get the same result: green and amber blinking lights.

I'm thinking about buying a new CF card, but I was hoping for some sage advice also...
