hmm, i am suspecting this might be a problem of mixing pygame 
subsurfaces and hardware surfaces. internally sdl might end up using 
software blits even on a hardware subsurface...

although i am struck with an idea to making this work. i'll see if i 
can add some logic to pygame to allow hardware blits to 
"passthrough" to the original surface, this should still allow all 
the speed of the hardware blitting.

if it works, we'll see it in the coming releases for pygame :]
