Sounds good, 2MiB should be what Windows uses for "large pages" on
processors that have these (in PAE mode or on x86_64).  I'm not sure if
it still needs nudging to boot w/ PAE enabled, it would use 4MiB large pages
when not in PAE mode, but the large pages are not exposed to the
application layer on Win2000 and WinXP anyway.

Achim.
