  (2) make page table entrys 64bit wide in PAE mode only.
  (3) pass two values: 32bit page frame number & flags.
  (4) others?

I'd prefeare option (1), option (3) is reasonable as well I
think.  I don't think (2) is a good idea, that will cause some
very nasty problems in case we'll try to allow non-PAE guests in
PAE mode.

Comments?

I like option 3.
