It appears I had not compile the fglrx module with the correct symbols 
defined (it seems to like CONFIG_X86), so after some hacking this is 
what I have:

(from dmesg after loading intel-agp and fglrx):


Linux agpgart interface v0.100 (c) Dave Jones
agpgart: Detected an Intel i875 Chipset.
agpgart: Maximum main memory to use for agp memory: 440M
agpgart: unable to get memory for graphics translation table.
agpgart: agp_backend_initialize() failed.

fglrx: module license 'Proprietary. (C) 2002 - ATI Technologies, 
Starnberg, GERMANY' taints kernel.

Non-preemtible kernel gives a similar error.

Has anyone played with this before? I am using the latest xeno-unstable 
from bkbits.
