All those interested,

Here's how I solved this (kind of dirty, but it worked).  

1. I hacked site-packages/xen/xm/create.py and added a couple of new
options that can be specified in the domain config file (IP, gateway
etc). 
 
2. Those options were passed to the kernel as parameters and then I
grabbed those parameters (they're set to environment variables) in
the /etc/init.d/rcS init file and created a
custom /etc/network/interfaces with them.

Let me know if you have questions about how I did this or any better
suggestions.

Michael
