In fact, that's what I suspected as well.
Is there any way this bios bug could cause me further trouble?

It appears to work properly.
I have been constantly running the radeon driver for 3 days only so

that period. I'm currently enjoying the increased 2D performance the
free radeon driver offers me, especially with video playback.
Can I provide more useful information?
