Hardware overlay on G965

[Thomas Fritzsche]

Hi Maxim Levitsky,

Yes, so I got interested about your patch.
In the final version of the Ubuntu-patch
(http://launchpadlibrarian.net/9337645/xserver-xorg-video-intel_2.1.1-0ubuntu3.debdiff)
I read:
+  * debian/patches/01_fix_compiz_video.diff:
+    - default to overlay mode on hardware that supports it to
+      make compiz video work

So I thought you patch is helpful getting overlay more activated.
(what it doesn't do for i965 without your patches)

Meanwhile I tried to research and it looks like my X3100 uses a GM965.
I guess the "M" means "Mobile", so your patch can't work?

I try to find documentation about what i965 flavour supports overlay
and what not. I'm digging around
http://intellinuxgraphics.org/documentation.html but have not found
the details.

Thanks,
 Thomas
