Okay. Looks like you need to be put back into your place with a big helping of
shut up, you don't know what your talking about. Again.
First: The driver charts show that AMD's plan is working. Their intent was to move legacy product users off to an Open-Source driver that would better suit their needs. This enables AMD to focus their paid FGLRX developers on optimizing for a small sub-set of the available cards. This enables AMD to turn around driver updates faster, and on a more regular basis, as they eliminate or minimize potential regressions. This means that those who want to keep using their ATi cards can still continue to use them, indefinitely, against any kernel changes, API changes, or library changes.
Those who whined and complained because their previous high end x800's, x1800's, and x1900's suddenly became unsupported are a non factor. Fact is, if you like to game in Linux, you'd have long upgraded your graphics card from the series AMD discontinued. End of story.

Second: AMD's not the only one to drop support for cards. Nvidia does it to. So far they've dropped support for the DX7 cards, then the DX8 cards, then the Geforce FX series. Now you might think that because Nvidia has moved these to a
legacy driver it means they are still supported.
Um. No. Thing is the feature list on the X.org ATi driver is still expanding. It's getting new capabilities, better performance, and offering a better experience when just about every update. When Nvidia terminates support for a card, that's it. No open-source sponsored driver. No recognition of a non-supported open-source driver. No further bug-fixes. That's it. That's not support no matter how you try to classify it.
This means that you are dependent upon Nvidia to update their legacy drivers against any kernel changes, API changes, or library changes. So far Nvidia has kept up. But what guarantee do you have that they'll continue to do so over the next 3 years? If that was your reason for buying Nvidia over ATi for the laptops you talked about above, that's one of the most pathetic reasons I've ever heard of.
***
Third: Just because ATi manufactured a chip and somebody else sells it, doesn't mean ATi is still making the chip or supporting it.
Case in point: Over at
Newegg you'll find that Radeon 7000 and 8500 GPU's are still on sale.
Just because a vendor sells a product that has been moved to a maintenance or retired state, does not mean, nor indicate, that the original chip supplier is still bound to support those products.
