Are you limiting the memory for dom0? If so I suggest you allow it more, 
or don't limit it at all and see if it boots any more successfully. It is 
also probably worth booting direct to run level 3 (add 3 to the boot 
line) to so you can eliminate whether or not graphics is an issue.
Also I suggest you check whether the hypervisor and xen software are the 
same version. If they aren't then xend may not be able to the hypervisor.
