Usually bugs in the driver don't affect such different chipsets, but this actually looks like a bug in mesa, and not in the driver. The error comes from Mesa-7.2/src/mesa/drivers/dri/common/dri_bufmgr_fake.c in the source package mesa (http://packages.ubuntu.com/source/intrepid/mesa). It's line number 987 in http://cgit.freedesktop.org/mesa/mesa/tree/src/mesa/drivers/dri/common/dri_bufmgr_fake.c?h=mesa_7_2_branch&id=75b8d0209c62e696714abf16782804c5a14159cf .
There has been one update to this file after mesa 7.2 was released (http://cgit.freedesktop.org/mesa/mesa/commit/?id=75b8d0209c62e696714abf16782804c5a14159cf) fixing a bug http://bugs.freedesktop.org/show_bug.cgi?id=17705 , but I don't know if that bug is related to this one.
