I got a little question not related to the problem of the thread's author, but it's about performance as well:
In what ways can preemption or the kernel framebuffer affect 3D performance of a graphics card? As far as I know, PREEMPT only makes the kernel able to interrupt it's work which is good for userspace apps and the framebuffer is only working on the virtual consoles.
I have enabled PREEMPT and I am using the VESA framebuffer as well, but I think my system is running somewhat fast and reliable (3D as well, i.e. UT2k4 has usually more than 100 FPS, sometimes above 200 at 1024x768 AA and AF disabled, with a P4 2.0 GHz and a GeForce4 Ti4600)
