OK, the radeon manpage says that's the rv505/rv515/rv516/rv550, so definitely the r300 (thru r5xx) driver. That one's somewhat more mature than the r600 (thru r7xx) driver. You've had OpenGL support for some time. 1680*1050's likely fine, but you might have issues running double that (dual monitor like my 1920x1200 stacked for 1920x2400). I don't know the real detail on that driver tho, as I rather skipped that level of hardware. AFAIK, that driver got KMS the kernel before the r600/700 driver did, so I think you should be able to get it with kernel 2.6.31, tho the kms-by- default option was in the kernel staging drivers area until 2.6.33. With 2.6.33 it's in the main driver options, now. Certainly for the r600/700 driver, 2.6.33 is HIGHLY preferred. I don't believe it makes as much difference for the r300-500 driver. Also, while Nikos is absolutely correct about wanting kms and the absolute newest stuff (even not-yet-released) for the r600/r700 driver, I'm not sure it's such a big deal with the older r300-500 driver, tho if you do any outside-X work at all, you'll almost certainly want KMS once you see how nice it is. But I do think the OpenGL support is actually better with KMS off on the older hardware/driver, at least until kernel 2.6.33 and the upcoming mesa and radeon driver releases to match it, at which point kms will be preferred. -- Duncan - List replies preferred.
