Thanks Chris, this is very useful.

It would be helpful if you could use a debug=y build of Xen and add a
show_guest_stack() just before the BUG(). Further, it might be revealing
to hack the following into linux-2.6.11-xen0/kernel/printk.c:vprintk to
see how far the dom0 boot it is getting.

It's important to ensure you are using a debug build of Xen (debug=y make). Also, the guest backtrace will not be in a particularly pretty format. You may just want to post it here but we will definitely also require a link to your vmlinux file (i.e., non-compressed Linux image that has not been stripped of symbol info). We can then match likely addresses in the backtrace to code points in the objdump'ed kernel image.
