I think .ko would be kernel object... then again, I dont know squat...
When I try to compile ALSA 1.0.0rc2, I get a 'PDE redefined' error... I haven't been able to find ANYTHING bout that anywhere... I THINK PDE stands for 'proc dir entry' or something like that... I tried stupid workarounds like just commenting out all PDE related stuff in the configure script, and in the header files from where the error comes... no point, just to see what would happen, and maybe figure out how to get around it... but no luck so far....
