I don't think I do - once X is locked up it just spins there. On the other 
hand maybe I'll see them if I start X by sshing from another computer.

Also, I seem to have lost the ability to trigger lockups with x11perf.
Strange, as it used to be I can do it repeatedly after a clean boot..

Could you try to do this:

In X.org 2d driver, find file radeon_dri.c, function RADEONEnterServer and 
try disabling the R300 piece with the long comment.

I am curious to know whether

     a) You still see lockups with this disabled

     b) I would expect the 3d driver use to cause lockups without it - but
        it might not, if not it would be a very useful piece to the puzzle.

                    thank you
