Bug#374986: System crash with enabled DRI

[Patrick Plattes <patrick@erdbeere.net>]

I can reproduce it.

If DRI is enabled (Load "dri") in the xorg.conf the system hangs 
after/while starting the x-server. After I've commented it out 
everything works fine, but of course not as fast as it could. There is 
no way to shutdown the system, because the keyboard doesn't work. It 
occurs with the open source radeon driver _and_ the closed source fglrx 
driver, so it's not a problem ox the xserver-xorg-video-ati package, I 
think. There was a problem in bug #355811 and it was fixed. This bug 
looks also like mine.

Hardware:
ATI Radeon 9200SE (RV280)
AMD Sempron 2800+
K8T800Pro

Most recent etch packages :)
