Hmm, may be.
I also thought that the surface sync packet has some special case optimzations 
for some of the probably often used flags that lead to that kind of behaviour.

May be that 'flush all' in case of a new framebuffer target for these kind of 
chips is again a good idea instead of the finegrained flush dest caches.

May be Alex finds some undocumented ideas somewhere in his bag :).

Greetings and thanks for looking into this!
