the warning here means: "the BIOS messed up but we fixed it up for
you just fine".

Should we print a DMI descriptor so that it can be tracked back to the
bad BIOSen in question? Or should we (partially) silence the warning
itself? Those BIOS bugs need fixing really: older kernels will boot up
with bad MTRR settings - resulting in a super-slow system or other
weirdnesses. We can tone down the message so that it doesnt show up in
kerneloops.org. It's up to you.
