I have an nVidia GeForce Go 7800 connected on a PCI Express 16X bus which is working very well under Xorg with FreeBSD Current and the nvidia driver from ports. It's connected to a 945PM chipset from Intel. So far it's been very stable and it's been giving me very good performances with UT2004 and Quake3. The only time I've got crashes what when I tried to use one of the raster modes on the syscon console. The system would crash trying to map the syscon framebuffer when I switched to any vt. Steph
