Xensource seems to have a couple of developers working with upstream Linux now.. 
upcoming Linux 2.6.27 will have more Xen domU pv_ops features (64b support
etc), and they're working with getting Xen dom0 pv_ops support merged in..
some groundwork already sent/submitted for 2.6.28.

Too bad they didn't start working with that stuff earlier :(
