That is correct.
The upstream -tip tree currently has some 64 bit domU patches queued
(probably for 2.6.27). They are rather new and far reaching since they
make some some nice infrastructure cleanups along the way etc. There's a
rather slim chance they might make it in for Lenny but given their young
age I'm not quite happy to say we could support a kernel with them for
the lifetime of Lenny.
dom0 support is being worked on by Fedora people (I think) but there are
no patches upstream yet.

FWIW fc9 didn't ship with dom0 support -- that is targeted for fc10.
For now I think they recommend you stick with fc8 for dom0.
I think we will be in a similar situation -- recommending sticking with
Etch for dom0 (or at least the Etch kernel, which I run on sid for my
Xen uses just fine) is probably the best we can do at the moment.

Without a massive injection of manpower (Debian side or upstream) I
don't see much changing. I've heard that maybe a Lenny + 1/2 kernel
might be able to add the features (64bit + dom0) which are missed this
time around if they are available upstream, but that isn't my call to
make.
