There's been a long standing issue on detecting the full 4M on controlfb
that regularly pops up. I happen to have a 7600 with the video upgraded to
4M, so I've been interested in this as well. I've seen several patches
float over the list, and I don't think any of them actually worked for
everyone. I believe the conclusion was that control just didn't act the
same on every machine. I suspect that if you look back through the list
archives, you'll find lots of discussion on this topic.
