Debian wears out my patience

I’ve been happily running Debian on my ThinkPad for over a year, probably the longest time I’ve ever kept a single OS on the thing. Or rather, I had been until Saturday. Saturday is when I decided to update my X.org. I’d had some problems with X.org before. Debian Testing upgraded to X.org 7.0, and it turned out the ATI FireGL T2 drivers in that were broken. So, no fancy new X.
