I don't know. Maybe I'm just reading the data book wrong. Please hit
me over the head again in that case.
It says bit 5=1 (0x20) and bit 0=0 => Unpredictable behavior occurs.
0x02 is write-allocate. Why do we want to do that?
0x21 on the other hand, is uncacheable+write-serialize and sounds
more like what we want.

Anyway, I imagine that this will be needed for more chips. How do you
feel about moving the MSR:ing to a handy helper?
