Xorg server 6.9.0 hang on ATI Radeon 9600 (RV350 AQ) with dri enabled

[Guy Helmer]

I just upgraded my FreeBSD 6 workstation with 6.1-PRERELEASE amd64 built 
Feb 7 2006 to Xorg 6.9.0 only to find the standard X server seemed to 
hang at startup using 100% of the CPU in system mode (I was able to 
login from another system via SSH and run top(1) to see what was 
happening). It's an Athlon 64 system w/ Asus A8V motherboard and ATI 
9600 (ATI Radeon 9600SE AQ (AGP) chipset, according to Xorg.0.log.  
kldstat showed radeon.ko and drm.ko were loaded.  I've re-built and 
installed the dri-6.4.1,2 port with no change in results.

Commenting out the 'load "dri"' line in the modules section of xorg.conf 
has made X usable again for me.  I see a thread from Chris Shenton 
<chris at shenton.org> (although the subject was "Xorg 8.9.0 [sic] "radeon" 
with DRI hangs FreeBSD-6.1, OK without DRI") that doesn't seem to have 
come to a successful resolution...

Any thoughts?
