Here is my xorg.conf for:
lspci output:
"VGA compatible controller: ATI Technologies Inc Radeon Mobility M6 LY"

This is now nice and snappy with window rendering and all the corruption issues have resolved. Scrolling in Firefox is also fine. If I try to enable compiz, the whole system freezes, but since I don't bother with it on this old 1 GHz celeron notebook, I don't miss it.
