Radeon x300-x800, Xvideo and DRI?

I've been trying to get my hands on some recent information regarding
the support level of x300-x800 Radeons. From what I can tell, they
should basically work, and DRI is available though experimental.
However, I have some specific questions:

Does Xvideo at least work reliably for these chipsets, or at least some
of them? I can live with mostly solid 2D+Xvideo support for now, though
at least semifunctional DRI would be a nice bonus. Hence, are there
major differences with the stability of the DRI driver between x300,
x550, x700 and x800? Basically I'd rather buy in the low end, not being
very needy in this respect, but if those chipsets happen to work less
well for any reason, I can aim higher.

Possibly relevant information: Setup would be Ubuntu Linux, AMD64X2,
PCI-E, 2x1600x1200 VGA monitors. I know the caveat about r300 and
2560x2560 total DRI rendering area, and can live with it. Can aid in
debugging, though not actual development. I don't expect everything on a
silver platter.

(Oh, I was trying to find a card capable of driving a dual-link DVI
2560x1600 LCD using free drivers, but those seemed to be in nonexistant
supply, hence I've shelved my display upgrade plans for now. If I've
missed something with respect to this, I'd be glad to hear it.)

Thank you for any information.
