X.org hanging under 7.2-PRERELEASE

I update -STABLE about once a week. On Wednesday I update, and subsequently 
started getting hangs and lockups. This happens only when DRI is enabled. When 
DRI is disabled there is no problem. The seriousness can vary. Sometimes I can 
ssh in from another machine to reboot, other times I can't. The last time it 
hung, top showed X.org at 100.0% CPU. The previous time it was stuck with in a 
"drmwtq" state.  The hang always occurs within twenty minutes of starting X.

Particulars:
FreeBSD 7.2-PRERELEASE #2: Thu Mar 26 19:21:26
xf86-video-ati-6.12.1 (with Radeon X1550)
kdelibs-4.2.1_1

Relevant portions of my xorg.conf:
Section "Module"
    Load  "extmod"
    Load  "dbe"
    Load  "dri"
    Load  "glx"
    Load  "xtrap"
    Load  "freetype"
EndSection

Section "Device"
    Identifier  "Card0"
    Driver      "radeon"
    ...
    Option      "AGPMode" "4"
    Option      "RenderAccel" "on"
    Option      "AccelMethod" "EXA"
EndSection

I have had no prior problems with -STABLE. I have an Intel Q45 chipset, so I 
need to run -STABLE, and don't have the option of going back to -RELEASE. Is 
there any easy way to go back to an earlier -STABLE?
