Radeon 6450 + Mesa 9.2.5 + compiz

[Mariusz Wawrzyniak <rowerek%gmail.com@localhost>]

Hi,

it's just "me too" post, (after Matthew Green's post from 17 Sep), 
but with different graphic card and maybe some differences 
in error output.I built fresh kernel (today's with radeondrmkms 
in GENERIC), made the same trick as Matthew with r600_dri.so in 
/usr/X11R7/lib/modules/dri/ and launched X's with compiz from pkgsrc.
 Everything runs almost fine (except some artifacts, color inverted small
areas on gtk apps, etc.) until I run more tabs in firefox.  
Computer reboots, dumps the core and later /var/log/messages look 
like this:

I can send core file if needed, and(or) other infos.
I'm using NetBSD since 4.0, so it's damn good thing to see desktop
effects for the first time on this system :)
Thanks for Your work.
