Found ( what I think is ) the problem:
[   440.478] (II) EXA(0): Offscreen pixmap area of 47104 bytes
vs.
[   160.890] (II) EXA(0): Offscreen pixmap area of 1083904 bytes
The latter is wrong, going to find out how we got there...

The -current driver uses SX for a lot more xrender operations than the
code in 9.2. The thing isn't fast compared to modern graphics hardware
but it sure beats pure software.
... which probably makes SX the oldest graphics processor we can use
for xrender.

have fun
