Hi

It doesn't fix decoding (for my 9600) - which that bug is mainly about.

It does avoid the crashing with s/w decode that r300 had because npot 
wasn't enabled and the one case I found that mplayer would crash on r600 
mentioned in the bug is also fixed.

Unfortunately it's not quite right, there's an artifact on r300 s/w 
decode = thin green lines right and bottom.
R600 with the patch doesn't show it as much, but 1080 stuff does have 
one at the bottom.
