I'm with 8.42.3 and Sapphire HD 2600 XT and I'm feeling very stable with my Debian Lenny. Maybe some bug fixes in pre-R600 will be well met. Because my brother's Mobility Radeon X700 is really blazing(compared to 8.35.5), but there are artifacts that many people have complained about. I have not other complaints about 8.42.3.
Any hint as to when ATI/AMD will release the 3D specs?
I know people have discussed the possibility of non-disclosure or proprietary elements within the chipsets, but I wonder if they are looking at 2D to be rock stable across 80% of the chipsets in production before they release the docs?
