Of course you can compile Xen on Debian :) 

I guess this thread started about the debian kernel group meeting:
http://lists.debian.org/debian-kernel/2009/10/msg00613.html

.. where they say next stable debian release ("squeeze") will have xen
dom0 kernel using forward-ported xenlinux patches (from novell/opensuse), 
and after squeeze release the separate xen dom0 kernel will be removed from 
debian, 
since by that time the pv_ops dom0 support should be included in the upstream 
Linux kernel.
