I know the Xen 4.1 release is imminent, but maybe somewhere here could spot the 
problem with a quick look at the boot messages (
        xen 4 hv kernel panic.txt).

Paul's not using upstream Xen, but Debian packaged Xen 4.

The bare-metal kernel boots fine on Paul's machine, but via the hyper-visor it 
does not.
