Well, this is why its in unstable. Also, PAE does not work due to broken
dependencies on compat VDSO. Its a work in progress ... hence unstable.

Well, why would they? Proporting to a kernel that is 5+ versions ahead
is a huge amount of work. So lets say they started, released it and a
month later dom-0 ops appeared in mainline .. that would be an egregious
waste of talent. What sucks is the unknown, when is it going to hit?
Most distros are banking on 'soon'.

I would agree though, if dom-0 ops do not appear in mainline in the next
few months .. its time to jump kernels, if only for re-staging the
patches for another try. However. at this point, its best to see what

Have you ever dealt with Linus on a major patch? It gets ugly, quick :)
Debian/SUSE has moved the xen-0 stuff to an agreeable place, work
