Please don't do this yet.  7.6 does have r600 support, but it still has
some bugs that make it really unusable in compiz or kde4.  The primary
issue in 7.6 is text and menu corruption under compiz/kde4.  Basically,
most anything you type is displayed incorrectly.  7.6.1 is due out any
time, which has those issues resolved.

It's also possible that we might have issues with libdrm, but I don't
know that for sure right now.
