Agreed. Although you have to be careful on AGP voltage.

Normally, anything NV28 or newer is AGP 3.0 _only_. That's a major
issue when it comes to voltage:

But the NV18 (MX4000) cards are typically designed to be universally AGP
1.5/0.8V across AGP 3.0, 2.0 and even 1.0 (with rear exception)

The DRI/UtahGLX support for nVidia is pretty much NV0x only (maybe
NV10/15 limitedly) and _lacks_ features for compiz last time I checked.

Those developments were based on -- and I wish more people knew this --
nVidia released 100% of the source code in the XFree86 3.3.x days,
changing identifiers and other things to protect IP.

Unfortunately, it didn't stop the lawyers from Intel, Microsoft and
others from sending cease'n desist letters. That's when nVidia decided
to move the 3D code to an unified model across all OSes, with a dynamic

Intel's IP is at the heart of ATI and nVidia's kernel driver. IP Intel
itself won't release for its own Linux drivers, but key to the unified
model. Long story.
