I see mtrr init (just the banner), but nothing about mtrr setup. And if this
contains a 2.6.12 boot, then there's no regression there.

I'm adding Thomas to the Cc, since he's supposed to be the expert here :)

Thomas, what could possibly cause such a drastic change in throughput to the sis
cards memory? MTRR doesn't seem to be used in either case.
