    Actually, if I'm not mistaken, you only need to cover the HT hole with
    one MTRR - the rest remains WB. And in order the mask bits to work, we
    could make it a little bigger - we waste some memory but that's nothing
    in comparison to the MCE.

    You might need to talk to hw guys about the feasibility of this deal
    though.

    Thanks.
