The mtrr looks like a generic X bug to me. We hit this with the VIA
driver too. The BIOS allocates an mtrr over part of the video memory
only. Unfortunately the XFree86 code to handle mtrr allocation is too
dense to deal with correcting it.

There is a patch for it in XFree CVS, and I've sent it to Dave Dawes.
Whether it will get into 4.4 I don't know.

However that isn't the problem proper. Your agp setup didnt initialize
and thats probably not loading the new per chip AGP module (this really
ought to have a PCI_MODULE_TABLE and get autoloaded but for most setups
its a hand fixup problem for 2.6 right now).

The mtrr error is just a slowdown.
