I also use the EeePC 900a but not with pure Debian but Sidux instead.  
I have not yet tried this with "real" Debian Kernels and this is why I  
didt not yet open a bug report.

But the story is as follows! The EeePC 900A still needs pciehp_force=1  
when loading the pciehp kernel module - even with the most up-to-date  
kernels. WLAN toggle will not work without pciehp_force=1 but it will  
work with it!

Here is what you can do to test this:
Reboot, then open a console and become root:

Unload the pciehp module:
# modprobe -r pciehp

Load it again with pciehp_force
# modprobe pciehp pciehp_force=1

You will now see that WLAN toggle works again without problems by  
pressing fn-F2


If you want to fix this permanently until the next eeepc-acpi-scripts  
update you can edit the /etc/init.d/eeepc-acpi-scripts file  
accordingly. This is what I have done but I would only recommend it if  
you at least understand how the file works and what to change -  
otherwise might break something.


I hope I will find some time soon to test this with original Debian  
Kernels (stable, testing and unstable). Then it'll be easy to patch  
eeepc-acpi-scripts accordingly to specially treat the 900A.

Andreas Schreiner
