Oh yes, so this machine has a bit of a complicated usable/reserved pattern. Which cannot be represented with only the 8 variable MTRR registers. The Linux kernel seems to give up and make it reserved, while Xen tries to use it because it gets marked unusable which is actually used as "usable for guest memory" somehow...
Hm Konrad, I wonder, Xen has detected the same and that sets it to unusable, but then unusable seems to be used in a different meaning. Should those cases maybe use reserved, too?
