7.12 & compiz - hangs

I have 7.12 installed on my thinkpad t60p (FireGL V5250) under RHEL 5., and it seems stable under non-compiz use.

I just ensured AIGLX was enabled, and enabled desktop effects. Unfortunately as soon as the compiz window manager starts, the desktop effectively freezes. Any running apps continue to run, but cannot be interacted with. Further an attempt to switch to a VT results in simply a flashing cursor top left.

The salient sections of xorg.conf includes

Section "ServerLayout"
Option "AIGLX" "true"
EndSection

Section "Files"
EndSection

Section "Module"
Load "dri"
Load "glx"
Load "extmod"
Load "dbe"
EndSection

Section "Device"

Identifier "aticonfig-Device[0]"
Driver "fglrx"
Option "EnableMonitor" "crt1,lvds"
Option "VideoOverlay" "on"
Option "DesttopSetup" "horizontal,reverse"
Option "DRI" "true"
Option "XAANoOffscreenPixmaps" "true"
Option "ForceGenericCPU" "no"
Option "no_accel" "no"
Option "no_dri" "no"
Option "mtrr" "off"
EndSection

Section "DRI"
Group 0
Mode 0666
EndSection

Section "Extensions"
Option "Composite" "Enable"
EndSection


Some lines are omitted for conciseness

Ideas? compiz is 0.5.2-1

Aftersome reading/some tweaks, Here's the errors I get

With my xorg.conf looking like this:
bash-3.1$ cat /etc/X11/xorg.conf

compiz is 0.5.2 -- latest binary rpms I could find compatible with RHEL 5.1 without rebuilding etc.

anyone got this working now?

What's the output of 'fglrxinfo' and 'Xorg -version'?
