> theres really no point in supporting HD5000 cards.

Problem is with Sam460 and X5000 users wanting to try out MorphOS on their machine bought originally for OS4. They won't change their graphics card just for that, so MorphOS should properly support whatever is in there, or will miss out on these potential users. So indeed, there's little point in supporting HD5000 cards, as HD7700 and newer is what Sam460 and X5000 use mostly.
