I received your kernel and the System.map in a private mail. Thank you, 
very kind of you. Unfortunately it produced the same result. Waiting for 
your mail to get trough, I decided to "hg clone" the sources to my home 
machine and try a compile there as well. It is running 2.6.14 Gentoo, 
but I suppose it shouldn't matter.
Both your kernel, my home-compiled one, and the ones I've been compiling 
in the test envirionment... all fail. Something is really strange. How 
come I can only run a kernel compiled out of the 2.6.12.6-sources from 
xen-3.0-testing... there must be something unique to this machine. Maybe 
I should reinstall xen or somethink. But that doesn't explain why a 
2.6.12.6-kernel works and a 2.6.16-rc1 doesn't... sigh.
Well. Now I'll take a weekends rest from this project. We'll see what 
happens next week.
Best regards
