Yes that's sounds good! And to say that i'm checkedout more about diffs with our cards and found something in wikipedia article. 9000 and 9250 both has 4/1 units, cards are with the same units setup, only rv280 has 8x AGP bus. And 9000 pro version is same, but with higher core and memory clocks and better bandwidth.

And then that's not a problem:(. I don't know what to say to the Mesa developers: I'm have hard freeze with current wine, with just one game when units are on default? Huh, I don't think thats will remove all this bugs.
