Yep.  I've also found that nVidia has been better about
supporting the 2D-only MIT drivers on newer cards before ATI,
although ATI _has_ been better in the last Xorg release (they
almost matched nVidia on cards supported by recent release

Yeah, that's the Xorg drivers you're relying on.

Although I believe the nVidia 6200-6600 (NV43-44) aren't
fully supported by the RHEL/CentOS 4 installer, and only the
6800 (NV40), although they will probably "work okay."  I.e.,
you won't need to use the VESA installer.

The newer Xorg release from a few months adds newer NV4x
support, and even some new G70 support.  But that's only for

The VESA installer should work, unless ATI is no longer
supporting VESA BIOS Extentions (VBE) 2.0+.  I haven't
personally checked if the new nVidia GeForce 7800 (G70)
series does, but I know all of the GeForce 6200/6600/6800
(NV4x) do.
