excellent. So just to make sure: this box never had proper graphics
under Linux (under no previous kernel), due to the way the BIOS has set
up the MTRR's, right?
so fixing up the MTRRs during bootup, no matter how dangerous in theory,
is pretty much the best option to get your system to work fine under
Linux, with that specific Xorg version?
i think we should still try to make this a non-default option because
modern Xorg should not have any need to touch MTRRs. Perhaps a .config
dependent on CONFIG_DANGEROUS ;-)
