Hardware overlay on G965

[Thomas Fritzsche]

Hi Keith and Maxim,

thanks so much for the update.
Meanwhile I patched the latest stable ubuntu (7.10) src package (intel
2.1.1) and everything seems to work nicely. :-)
Attached is the "quick & dirty" proof of concept patch.

I changed:
* Added: +#define HW_HAS_OVERLAY(pI810) (IS_I965G(pI810) || IS_I965GM(pI810))
(as I guess X3100 is supposed to have a i965GM?)
* I disabled the the texture video completely.
* minimal adjustment to version 2.1.1

So overlay adapter is used as default and all video application work
nicely with default settings in compiz.I have this nice little blue
frame when moving a window, but at least it works.

Only thing I notice is, that "top" shows me about 20% CPU utilization
playing a DVD. Is this normal for overlay playback?

Attached output of "xvinfo".

Cheers,
Thomas
