For 6 months now (since summer 2009) xen-unstable (the development version)
has been using pv_ops dom0 kernel as a default. pv_ops dom0 kernel is based on
upstream kernel.org git tree (of Linus), so it has been pretty much in
sync with the upstream Linux development. Currently it's at 2.6.31.6, but will
get updated to 2.6.32.x when the main developer gets back from his
christmas/NY break.
Upcoming Xen 4.0 release will use pv_ops dom0 as a default kernel.
So the change has happened, lthough it took painfully long to get the
upstream Linux pv_ops framework in shape and all that.. and obviously
the pv_ops dom0 patches still need to get merged upstream.
pv_ops dom0 kernel definitely needs more testing still, so now it's a
good moment to do some testing, if you're interested of this stuff.

If pv_ops dom0 is not what you want, there are many other Xen dom0 kernel options aswell:
