On a x86-64 host with a HD3870 running 2.6.39-2-generic (from ubuntu's oneiric)
and

libdrm-2.4.25 and mesa compiled for 32bit:
OpenGL renderer string: Gallium 0.4 on AMD RV670
OpenGL version string: 2.1 Mesa 7.11-devel (git-390196e)

I get lightning artifacts with r600g on a couple of games from frozenbyte.com,
most notably when using the flashlight in shadowgrounds.

Here's a apitrace capture:

When replaying it via glretrace there're some weird window resizes, but the
issue is visible when it doesn't crash :)

The issue does not exist with swrast.
