I don't know *anything* about debian, but check to see if the way you are 
hiding the
device is right, rhel doesn't use the grub method anymore, but a loadable 
module.
You need the correct lines in rhels modprobe.conf, then you make a new initrd.

Does 3.2.0 have support for pass through to an hvm? I thought that was new to 
3.2.1?

What's your hvm conf look like?
Your xen logs have anything to say about the entry in the conf it see's while 
starting the domain?
