I have tried with 640x480, 800x600 and 1024x768 and the upper limit seems
the same (I've also tried some combinations of resolution / BPP)

scrolling is a bit faster and I don't notice any additional screen
corruption

time cat MAINTAINERS (2.6.9-rc1 + your patch / 800x600 8bpp / YRES 3200)

normal: ~0.19
without banshee_wait_idle in the three functions: ~0.12
