Ok I think I'll haveto start over again ... let me reedit the whole thing:
The eeepc user forum and wiki only treats customizing kernel with same bersion and same build environment (yes using modules built with different compiler than what was used on kernel will most likely make them unusable) ... so here I am trying to put up some info on how to put up a generic vanilla kernel on eeepc.
So how should one configure the kernel ?
I have found out by experience that taking your .config across kernel releases might work but may lead to problems.
So I allways start out with a make mrproper and configure it from scratch ... this is a long and tedious process ... YES
Take the /boot/config-18.104.22.168-eeepc as a guide and enable and disable features you need.
You can safely disable the asus-laptop because it just will not work.
I aslo enabled a few more usb devices and had usb-storage built into kernel (for booting of the SD).
Do not use the ath5k kernel driver because it jus won't work yet with the atheros device in the eeepc .... instead use this
wifi driver which is also part of the madwifi project.
The atheros LAN device is not yet supported in the kernel so use this LAN driver to get the atl2 worling. If you are building with a kernel version diffrent to what the target will be you will haveto make some minor changes to the makefile.
I've managed to get the wifi led turn on and off with a third party asus_acpi module source and a patch .... but it fails to actually turn on the wifi device .... I'll update on this as soon as I find a solution.
