About the xorg.conf: The lines about shadowfb and composite are commented for
radeon, but are normally uncommented for radeonhd. (Composite is disturbingly
slow with XAA/EXA.)

So, I tried again, but for some reason I can't log anything from inside
RADEONSetupImageTexturedVideo. I can kill the X server from inside that
function with something like:

int* seg = 0;
*int = 7;

So I know for sure that it's hanging somewhere in that function. But,
xf86DrvMsg doesn't work inside there, and I don't know how to load X into a
debugger, so I'm stuck.

Oh, and if I do segfault the server, my screen is still hosed; it's completely
blank and the backlight is off, like the connector turned off and hasn't turned
back on. (I know it's segfaulted because of things like:
    # startx && sleep 5 && sync && reboot
which does work if a segfault trigger is put in.)
