Aye this was rumoured a good few months ago.
You shouldn't really need updated drivers for the 'really old cards' anyway Robert, as you won't be playing the latest games on them, so that shouldn't be a problem.
Also, AMD has always had a growing corner of the market, which, although will be played down a bit with the release of Intel's Core Duo chips, it will still grow.
Compatibility has always been fine really between the latest cards and motherboards, and ATi infact have a group of people working on Catalyst drivers for all their new Graphics cards, releasing an update every month (IIRC), which fixes a lot of problems. You learn something new everyday
