If mesa doesn't get automatically rebuilt (changing VIDEO_CARDS counts 
as a USE flags change, so "emerge -uDN world" will pick it up), then 
that means you're using a version of mesa that doesn't recognize "r600".

I'm on mesa-9999 (one of the very few live ebuilds I use).  Now that I 
checked this, it's the only version to recognize "r300" and "r600" in 
VIDEO_CARDS.  However, that also means that future release versions of 
mesa will also recognize them (the live ebuilds are always a precursor 
of things to come.)  So adding "r300" or "r600" now doesn't hurt and 
will ensure you don't forget to do so later when mesa 7.12 (or 8.0?) 
comes out.
