I'm seconding this. r300g is working exceptionally well compared to r300
and it is very stable even with lots of 3D stuff and wine games. I'd
definitely want this to be the default in Arch. Perhaps we should file a
bug report. In fact, I will file one if we  can get a few more opinions
on this.

I think it would be a very beneficial idea for Arch users.
