I don't think there should be any difference between udev for native Linux and 
Xen-ified linux - the hint on configuring it "properly" was more to the point 
of "make sure it's set up". 

But I guess another point is that /dev/fbN is the "frame-buffer", which is only 
available on certain models of graphics cards - you may not be able to do that 
with the graphics card you've specified in the domain config (are you by any 
chance using "stdvga=1"?).
