You can specify the PCI ID to the driver (both radeon and fglrx 
drivers, IIRC)
to tell it which card to fire up xorg on (you'll need to create your 
own xorg.conf.
Make sure you blacklist the radeon kernel driver.

Do you catually need the fglrx driver in Dom0? Radeon driver does offer 
basic
acceleration. It's not great, but it's workable.

FWIW, the Nvidia driver _can_ be persuaded to work with Xen in Dom0
(see:

)
if you are considering a switch.
