No, I don't think I have any of them (cat cat /proc/bus/input/devices at the
end).

I didn't know where to find the script, Google gave me this:
http://git.alsa-project.org/?p=alsa-driver.git;a=blob_plain;f=utils/alsa-info.sh
So this is what I've use. I've shared the results at:

Well, my bad, I booted the wrong kernel when trying the patch. The patch
works correctly, so I'll be very glad if it hits Linus kernel soon :)

I could send you the patch but I don't know exactly what to put in the
commit message. The problem is the same as the one with the ASUS P5-V?

OK, thanks for the help.

I hope the patch is committed into the main kernel soon.
