Hi Pablo, sorry for responding that late. The boot option
(acpi_video_strict_detect=0) is only useful in Jaunty. Karmic is less
restrictive by default and from the dmesg I see that the acpi video driver
detects a gfx device. So in all this looks like a different problem and it
should get into
Tonight I upgrade the kernel with the last version for Karmic. It said there
was a solution for the brightness problem but it didn't work. I've tried
with and without the acpi_video_strict_detect=0 option and nothing
changed.
I keep waiting for a solution.
Thanks for your efforts.

I can confirm bug is definitely solved with Koala Karmic x64 out-of-the-

Temporary in Jaunty, when you see the grub screen go to the kernel you want to
boot, type e, go to the (I think 3rd) line containing the quiet splash and
press e again, then add the argument and press enter, then b.
Permanent sudo vi /boot/grub/menu.lst then add it to the commented line

With a similar BIOS problem, brightness will not work on kernels after
2.6.28 and before the submitted patch hits upstream. It has been
submitted but probably gets not included before 2.6.32

brightness works out of the box (without boot parameter) with your proposed
kernel... here DMESG detail:
[8.769760] acer-wmi: Acer Laptop ACPI-WMI Extras
[8.770046] ACPI: Using less restrictive video detection
[8.770047] acer-wmi: Brightness must be controlled by generic video driver
Thanks for the quick test. I'll try to get that into the default kernel then.
Unfortunately for the problem with the key I would not put too much hope into
getting it fixed in Jaunty. Karmic is nearing its Beta and more effort will go
into that.

I think from the debugging point you could update, but as I did not have
time to work on a special patch, you would be back to no brightness
