There is. It states that the latest drivers or features are only
available in linux-core for 2.6 kernels. Also Alex added a specific note
about the Savage driver yesterday.

If you really want to do this, then an empty host.def would be a good
start. You may want to keep some custom compiler optimization options
though. And "#define NothingOutsideProjectRoot YES" is a good idea too.

You could experiment with AgpMode and AgpSize in xorg.conf. Also lower
resolutions and refresh rates tend to improve performance slightly. But
don't expect any miracles. 380 FPS on gears is quite good for a
Savage/MX. I get about 350 on a Savage/IX.

It has nothing to do with the display numbers. But only one display can
use the DRM at the same time. There was a patch for the Radeon driver
once that solved this problem by reinitializing the DRM on VT switches,
but the Savage driver doesn't support this now.
