Problems with xf86-video-ati driver (6.10.0)

Florent, I'm ccing you on this so you know about it.
On an Intel dual core box running 7.1 RELEASE and Xorg 7.4, the radeon driver
drives CPU to 100% and locks up the box. Keyboard and mouse input are ignored,
and it's not possible to switch to another tty to escape from the problem.
Kill won't kill the process either. You *can* login through ssh and reboot the
box to fix the problem (after editing the xorg.conf file first, of course.)
Loading the radeon and drm driver through loader.conf did not change any
behavior.
There are no errors in the Xorg.0.log file, and the process of X startup
appears to be perfectly normal. Switching to the vesa driver fixes the problem
entirely. The radeon driver can be used, less than optimally, by disabling DRI.
Option "DRI" "off"
I looked at the latest driver at x.org (6.10.99.0), but I didn't see anything
in the notes that indicated that this problem might have been fixed.
