Hardware environment: Asus Eee PC 4G (Black Galaxy)
The wifi chipset - Atheros AR2425 (AR5007EG) - is identified, and the propietary drivers are loaded.
Sadly, right now, wifi can not be used unless you install the appropriate patches. The dmesg command shows an error message: Hardware revision not supported, so the driver has not support for that piece of hardware.

Hardware on the Eee PC according to the original Xandros: Atheros Technology Corp. L2 100 Mbit Ethernet Adapter. Ubuntu 8.04 detects it as Attansic Technology Corp. L2 100 Mbit Ethernet Adapter and loads the correspondig drivers (atl2). The wired network seem to work properly. I have found just a small bug in the counter of the outbound traffic (always zero).
The original Xandros uses
Atheros(R) L2 Ethernet Network Driver - version 220.127.116.11
while Ubuntu uses
Attansic(R) L2 Ethernet Network Driver - version 18.104.22.168
As you can imagine Atheros and Attansic are just the same right now.
Suspend: You can suspend the computer (it takes a long time but finally it does suspend). When you restore, everything seems to be right. The only small detail is that the screen brightness does not maintain the previous settings. The screen brightness is set to max when you restore. You only have to adjust the brightness.
Power off: The live CD powers off properly. Once installed you have to press the power button for several seconds to power the computer off.
CPU frequency: Not tested
It seems to work right. Some ocassional strange noises. Maybe not still 100% supported, but it works well enough to be usable without modifications.
The video camera works out of the box. just be sure to have the camera enabled on the BIOS. The system loads the uvcvideo drivers and the camera is just ready to use.
I have tested the suspend, Wifi on/off and brightness adjustment buttons. They work properly with no need for previous configuration.
