Does your xorg.conf reveal anything of interest (errors)?
What graphics card are you using?
I'm using a Radeon 9500 Pro.
I take it you mean Xorg.0.log But no, no errors or even notable warnings there (just that there's no mouse specified etc). The last three lines logged are
(II) fglrx(0): Acceleration enabled
(II) fglrx(0): X context handle = 0x1
(II) fglrx(0): [DRI] installation complete
and then X hangs and I have to reboot.
Interestingly enough, when I tried to revert back to the radeon driver (after first building the ATI driver myself, then trying livna.org's version) it didn't work either - it, too, caused X to crash, with
Hell, I'll probably never be able to go back to the open source radeon driver, but I'm happy to report that I've solved this problem (the "how exactly" part is a bit unclear, though).

What I did (what exactly did the trick is unknown, though):
BIOS:
changed AGP Aperture Size from 128M to 256M
xorg.conf:
added into "Monitor" (these are monitor-specific values)
Which was fixed with a bunch of symbolic links (the /usr/lib/libGL.so.1.2 was the Mesa libGL when it should have been the fglrx one from /usr/lib/ati-fglrx/):
part in xorg.conf or AGP Aperture Size in BIOS, and I'd wager it was xorg.conf since I seem to remember changing aperture size before with no effect.
Removing the UseInternalAGPART part from the conf also (obviously) yields slightly better performance:

There are still a few problems with MPlayer (no XShape extension and OpenGL behaves a bit strange) but otherwise everything seems to be working OK (at least much better than it was).

...and adding
Load "extmod"
to xorg.conf Module section and restarting X fixed those too.
Hate to bump an old thread, but do you mind posting your entire xorg.conf?
I hit the same thing, even though everything was working a few days ago.
Uh, I would, but I no longer use this configuration, because it only worked for a while for me as well (it stopped working with the next driver update). So I no longer have that configuration file
Anyhow, I think it was the Phoronix recommended xorg.conf with the modifications I mentioned. There really was nothing fancy in the configuration file. Something just suddenly made it work, and just as suddenly it stopped working.
