I didn't do anything to get it to work with the closed source drivers on Linux 
or Windows. Presumably, I have just gotten lucky in terms of hardware choices 
or Kantras has included the perfect set of patches in the Arch package. I 
didn't do any sort of "blacklisting" in the Dom0. I just use "xl pci-
assignable-add" on the devices I want to pass trough. My configuration file is

name = "Arch"
builder = 'hvm'
device_model = "qemu-xen-traditional"
memory = 8192
vcpus = 2
disk = [ 'phy:/dev/mapper/vg0-arch,xvda,w' ]
vif = [ 'mac=00:16:3e:00:00:00,bridge=xenbr0' ]
pci = [ '02:00.0', '02:00.1' ]

where vg0-arch is an LVM volume and the PCI devices 02:00.0 and 02:00.1 are 
the graphics and sound devices on the AMD 5450. The windows configuration file 
is essentially the same.

In the Linux DomU, I just installed the catalyst package 
(https://wiki.archlinux.org/index.php/AMD_Catalyst) and everything works. 
Potentially the Catalyst package is blacklisting the Radeon driver in the 
DomU, but I am pretty sure that is not what you are talking about.

In the Windows XP DomU, Windows Update found a driver. All I had to do was 
disable the virtual Cirrus video card in device manager.
