It (the unstable patch) did not apply cleanly to the latest snapshot so
I did some minor fiddling.  The resulting patch (attached) works fine
and testing so far yielded good functionality. Great work, thank you
very much!  

A question to Xen maintainers: is the roadmap towards resource
management (grant tables) pointing in this general direction (=will
Christophers changes be included in some way in the future), or will it
be finally more something like Xenidc?
