No, you have misunderstood.   I removed that Radeon rv610 card (that 
caused the kernel oops) from the machine and replaced it with an old SiS 
card I have.  The behaviour changed: now the Xserver locks up on 
initialisation and consumes 100% CPU.  The backtrace I provided is with 
the SiS card only.  I thought it might be helpful to locate the problem 
(assuming that we are seeing a different symptom of the same underlying 
problem).

BTW, my attempt to CC the xorg mailing list failed.  It would seem that 
they are too exclusive to allow posting to their email list without 
subscription.  Putting up such barriers means they won't get bug reports 
from such people as myself.  Their loss.

Cheers
Michael
