radeon pci ids in driver/xserver...

The whole DDX/DRM/DRI interaction could use a freshening in fact :) But
that's something I don't want to bother too much about before we have
recovered some stability out of radeon and I'm happy enough with the
1-0-0 branch to do a release. Right now, I still need to figure out some
known regressions with MergedFB and Xinerama.

Oh btw, you are the MergedFB guy no ? If yes, can you just have a look
at bug #4100 and tell me what you think ? Some co-workers of mine have
been hitting the crappy DPI problem with MergedFB/RandR here too and
it's quite a pain in the ass...

Cheers,
Ben.
