This option doesn't have any effect with current upstream xserver and
KMS, and even with older xservers where it accidentally had an effect,
it's probably better to use the radeon driver option "EXAPixmaps" "off"
if you want to prevent acceleration on all pixmaps other than the
visible screen.

Might be worth trying the current X server and driver in sid first
though to see if they're doing better.
