X freezes with 2.6.32-5; okay with 2.6.26-2

[Kent West <westk@acu.edu>]

I've got an older 600MHz PIII running Sid; if I boot into the installed 
2.6.26-2-68 kernel, everything's fine, but if I boot into the installed 
2.6.32-5-68 kernel, everything's fine until X is started (either 
manually or with a session manager or even when trying to create a new 
xorg.conf file using "X -config"). At that point, the screen goes black, 
the keyboard stops responding, and the Xorg.log fills up with :

(EE) R128(0): Idle timed out, resetting engine...
(EE) R128(0): R128CCEWaitForIdle: CCE stop -9
(EE) R128(0): R128CCEWaitForIdle: CCE start -9
(EE) R128(0): R128CCEWaitForIdle: CCE idle -9
(EE) R128(0): Idle timed out, resetting engine...
(EE) R128(0): R128CCEWaitForIdle: CCE stop -9
(EE) R128(0): R128CCEWaitForIdle: CCE start -9
(EE) R128(0): R128CCEWaitForIdle: CCE idle -9

over and over and over until my /var partition fills up (assuming I 
don't kill X before that happens).

The only suggestion I found via Google as a possible fix was to append 
pci=use_crs to the kernel boot options, but that made no difference.

When the machine locks up, I can still access it remotely via ssh; it's 
just the local console that locks up.

Thanks for any clues/assistance!
