i tried the workarounds mentioned here:
http://www.linuxquestions.org/questions/history/270805

the ones by "urr" (on incompatible pointer type warnings) and a patch by
slacker775. i applied both these fixes and it's working cool!
btw, i'm running the latest 2.6.10-686 on hoary and am using 4.6.00.0045-k9
