I looked at the driver and got it working. However my 901 seems to  
have an issue with the antennas. I can do scans, but associating with  
an access point or even thinking about transmit keeps failing. Even  
with external antennas this still doesn't work. So either my EeePC is  
broken or it needs some ACPI magic to enable it. Personally I think  
mine is broken since the PCIe hotplug stuff works for the wireless  
card and that seems to be their way of doing the rfkill.

The driver itself is painful. It is full of ifdefs and some crazy  
build magic. The integrated (to some degree optional) WPA code is  
pretty ugly. It has also a full set of iwpriv commands to do all the  
settings etc. :(

Regards

Marcel
