Hm, interesting. What model (and BIOS version) are you testing with?

On my S10-3, (DMI BIOS version 2ACN23WW, date 03/12/2010), I get these
keys through the normal keyboard controller -- and we can tell the
brightness up/down apart, too.

Do you see those keycodes too... and do they *stop* arriving through the
keyboard controller when you load your driver?
