Hmmm... I spoke too soon.  We apparently have a number of customers
that use maxmem and would be upset if the functionality goes away.

If you can send more information about the "experiments",
I may be able to take a look fairly soon (unless Daniel Kiper
is already looking into it).  Since the support is currently
missing from RHEL6 beta, future customers using RHEL6 as a
Xen PV guest may get very confused by what might appear to
them as a tools or Xen bug.
