See the "x86-32 PAE" thread at http://mail-index.netbsd.org/port-i386/2005/=
07/.
General drift I get of it is that PAE is a ugly hack.

That being said, it appears that it may be doable (if much of the work
hasn't been done already).  But perhaps NetBSD/amd64/xen should be the prio=
rity.

Or, we just run plain NetBSD/i386 or amd64 like one would Windows on a
Vanderpool or Pacifica-enabled chip.

Hey, I know of at least two other places that are still running Xen 2,
and advertise NetBSD as a choice.
