I cannot run DirectX games since I switched to the "xorg-edgers" PPA, with uses
bleeding edge Xserver/Mesa packages and employs the Gallium renderer for my
Radeon Xpress 200M card.
The debug traces show that crash happens in r300_dri.so code:
"Unhandled exception: page fault on read access to 0x74dd3598 in 32-bit code
(0x7d10623a)."

Repeatable: always.
