    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
