This sounds OK, so it must be your specific architecture and version
combination.  I always used 32-bit hosts and Xen 3.2, so can't report
on anything else.  At least your problem is not the Debian installer,
but something more fundamental: starting the guest kernel.  Can you
start any 2.6.26 PV kernel at all?

I can't be of much further help, I'm afraid.
