The current Xen code needs 4MB pages (PSE) support.
There was a patch posted a while back to avoid this constraint,
but I don't think it was fully working. We'd be very happy to
incorporate a patch that adds support for CPUs without PSE,
providing it didn't impact the normal code too much (i.e. didn't
make it less readable).
