You can probably boot Xen somehow...  either using mbootpack and Apple's Boot 
Camp, or by booting Linux and kexec-ing into Xen.

Well what would be *nice* is if it were possible to port MacOSX to Xen and let 
it boot on top of Xen.  Then you could have it control the real display 
(pretty aqua graphics!) and run other domains with virtual machines.  
However, there are problems with this...

And that's the problem.   Unless Apple make it possible to compile custom 
kernels for OSX86, it's certainly not going to be possible to port it to run 
on Xen (and even then I'm not sure what the implications for their DRM are).  
Right now, you can't really have a dom0 that doesn't know about Xen, but 
there would be (relatively difficult) ways to hack round that if anyone 
*really* wanted to make it work (such as making Xen loadable as a kext after 
boot - this would require a fair bit of Evil Hacking but might work!).
