[Xorg-driver-geode] Still some bitmap corruption

[Cui, Hunk]

Hi, Sam,

	As you said it seems that there is still some issue with
compositing bitmaps in the geode driver 2.11.9-3, then run the
"evolution", but in my platform (the display resolution is 1280x1024,
Graphic memory is 24Mb, using the latest geode-driver), it seems OK as
in the screenshot (http://imagebin.ca/view/tQkE5TH.html).
	So I hope you can tell me the reproduce steps more detail, we
can trace this issue and follow it.

Thanks,
Hunk Cui
