I've tried quite hard on both 64 bit and 32 bit setups and with both patches applied can no longer get any corruption.
One thing I did notice is that there is a slight difference between running the sdl and glx versions, in that the sdl has a few strange chars in console - but it's the same with llvmpipe.
Are you running glx or sdl?
Can you get any corruption if you run it with the env
LIBGL_ALWAYS_SOFTWARE=1
