It's actually my patch from here:
http://www.botchco.com/alex/radeon/Xv/xv_alpha/radeon_xvalpha.diff
Vladimir committed it to gatos cvs a while back.

You can adjust the opacity of the graphics and overlay layers.  I only
implemented it globally.  there is also an option to do it per-pixel
but that required ARGB visuals which weren't supported at the time.
