At least for me, this doesn't help (and the cursor looks funky when its over a 3d app). I've seen several people with Go cards complain about this problem on their laptops.
I have an Alienware 51m w/ GeForce FX Go 5600. Mobo is a MSiS648FX + SiS963L AGP8X. I'm using RH9. I've tried smp and up kernels, both old and latest. My desktop is 1600x1200, 24 bit color, 60Hz.
I believe my driver installation is OK. OpenGL apps run and at speeds one would expect w/ acceleration working.
see this thead for a good description of what I'm experiencing. I have no trouble in windows, or with the vesa or nv driver (just no hw rendering).
