Its a Phoenix BIOS btw. 

For the WMI: Could acer_wmi be extended for this as Alex suggested ?
Another FSC model is listed in their hw-db.

Atm this is fine for me - being able to adjust the brightness in "some" way.
But this is not good for user/newbie xyz. How should he know the 
kernel-cmdline.


Sidenote:
I don't like this BIOS - there are just no features in it. I'm also struggling 
with vmx being disabled by the bios - and no menu to enable it.

TRAP 0x3D is the Windows WMI code then ?

I wonder what these two are ;)
