  Hi,

Trying to boot pv-grub on RHEL-5 makes it fail with

  [ ... ]
  gnttab_table mapped at 0x10001000.
  Initialising scheduler
  (XEN) mm.c:694:d6 Bad L3 flags 6
  ERROR: mmu_update failed
  Do_exit called!

Guess more recent xen versions are less picky here and just silenly
fixup this?  This is with 32bit pae.  64bit pvgrub runs fine.

Another issue:  As 64bit pv-grub can't boot 32bit kernels, the 64bit xen
build should create both 32bit and 64bit builds of pv-grub, so you can
boot 32-on-64 guests with it?

cheers,
  Gerd
