What an OS maker should do isn't write the driver, but they should provide the API, which is what Hyperion do. Writing the API allows the graphics card manufacturer - or in this case, A-Eon, because AMD aren't going to do it - to support the cards.
....
The alternative is simple - no support for later graphics cards at all. I think I prefer this option somehow. 
Well, you have it rather spot on.
Cheers!
