Ubuntu Feisty includes a restricted modules package that works with the Xen 
dom0 kernel though.  I don't know for sure that this includes a working fglrx 
kernel module, though - but it'd be cool if it worked out of the box, 
wouldn't it?

Actually, I suspect you can just go ahead an install fglrx if you don't need 
GL: the userspace portion of the driver is sufficient to do 2D, you just 
won't get 3D acceleration.  I *think*.

That'd probably work too, but I guess it'd be a bit gross for you to have to 
do that.

In what respect in particular?  I'll go ahead and babble about stuff I think 
is cool anyhow:

Xen isn't exactly a workstation-focused piece of software (KVM and VirtualBox 
are open source products that are possibly more suitable in some ways).  
However...  There's a neato project called VMGL 
(http://www.cs.toronto.edu/~andreslc/xen-gl/) which allows you to get 
accelerated OpenGL for a Linux virtual machine; this'll work with Xen and 
also with other VM platforms.

It'd be nice to see the framebuffer support extended to give better 2D 
acceleration in future.  It'd also be nice to see VMGL able to use a 
Xen-specific shared memory transport, which ought to be faster and more 
foolproof then the current solution of sending data over the network (eg. you 
can stuff up networking without Quake disappearing!).

Cheers,
Mark
