24bpp and 3D nvidia drivers

I am using Suse 8.0 with the latest nvidia with Asus GF2 32mb DDR but I cant get the system to use a color depth of 24 while keeping 3D support. Yast2 loads the 3D support fine but only lets me use 16 bpp. Sax2 will allow 24 bpp but for some reason seems to disable 3D support. Any ideas?
