Hello Linus,
is this BAD, then:

When I move my mouse over the OpenGL context window the OpenGL app runs
faster. But not as fast as before (last year "gears" had ~2800 fps, now ~800
fps).
Any change (kernel parameter) to set both aic7xxx (U160 and 2940UW)
controllers, the two NICs and the r200 on different IRQs?
Thanks,
Dieter
