MTRR fixup?

[Bernd Walter]

Some boards (including my Intel DG33BU) seem to have problems setting
up the mtrr to cache all RAM.
My system runs fast with 2G and ist about 6 times slower in buildworld
with 6G RAM.
I will try a BIOS update once Intels tells me why their update ISO
just turn the system off instead of updating the BIOS - sigh.
But it seems that Linux is doing some kind of fixup for MTRR:

Can we do something similar?
