i built a new 9pcf kernel from the latest sources that should have
included the latest vesa driver improvements (mtrr).  somehow i lost
the performance gains in the new 9pcf compared to a 9pcf kernel that i
downloaded from labs after geoff made the announcement.  ideas?

have you checked to see that the mtrr's actually cover the vesa memory
area and are getting properly configured?  i think some extra consistency
checks were added.

i'm still using PAT so i don't know.
