Hi!
First, I'd like to ask: what is status of ucb1x00 audio in 2.6? I do
have .c file here, but do not have corresponding header files...
Then, I'd like to announce that I finally got touchscreen to somehow
work. Patch is very ugly and adds filtering into kernel (no-no), but
does the trick, and can even coexist with battery reading code. [Don't
bother commenting on style of this patch, it is for ilustration, I'd
not be crazy enough to try to push it.]
