That's no good.  Thanks for reporting it.

The upstream report https://bugs.freedesktop.org/show_bug.cgi?id=33643
seems similar.

First, the boring questions:

 - can you reproduce it with the kernel from experimental?
 - can you reproduce it with the kernel from squeeze?
 - if it's possible to test without the virtualbox driver, does
   that help?
 - could you also attach the output of

	sh /usr/share/bug/xserver-xorg-video-radeon/script 3>&1

   for reference?

Aside from that, this should probably be investigated upstream, by
filing a new bug at http://bugs.freedesktop.org/, product DRI,
component DRM/Radeon, with as specific and reliable a reproduction
recipe as possible.

Hope that helps, and sorry I have no better ideas.

Regards,
Jonathan
