paravirtualized 32-bit on 64-bit host?

[Furnish, Trever G]

Anyone managed to get a paravirtualized 32-bit guest working on a 64-bit
redhat host?  The RHEL5.1 release notes claim there's preview support
for it.  If by "technology preview" they mean, "We tried it and it
didn't work", then yeah, I guess there's support.  But I'm having no
luck. :-(

Anyone else fairing better?
