I gave the testapp and patch a spin:

ipaq hx4700:

unpatched Xw100:  6.04 FPS
patched Xw100:    6.04 FPS
unpatched Xfbdev: 6.04 FPS
patched Xfbdev:   6.04 FPS

ipaq h2200:

unpatched Xfbdev: 4.18 FPS
patched Xfbdev:   4.17 FPS

Any clues why the patch doesn't seem to have an effect?

regards,

Koen
