ok, i am not getting the same kind of logs as you are. i cant imagine
our kernel configs are that much different. in the morning ill try
out your xconfig to see if it makes any difference.

ive never gotten 350fps, i think 60 is about normal - so im sure hardware
isnt being used now :)

how different is the performance for 3D with it not loaded? i built mine
directly in so i could be sure it wasnt a module problem.

if i do any kind of compiling or file copies, moving windows around
becomes quite a task. i was rather suprised how much the X was affected
by stuff like that. the friggin' 1200bps mouse doesnt help much either,
but my little soldering iron may fix that in the near future :)

i build a majority of my stuff into the kernel, so our kernel configs
are likely to be quite different. more tomorrow when i get into the
