Patch required for XV to work on XP5 chipset

The unpatched driver only displays a black window when attempting to display video via XV. Looks like XP5 chipset was just omitted in a few 'if'-statements in the sources.

This patch was tested on a ECS-532 laptop, lspci -v output:

01:00.0 0300: 1023:2200 (rev 02) (prog-if 00 [VGA controller])
        Subsystem: 1019:0f56
        Flags: bus master, 66MHz, medium devsel, latency 8, IRQ 11
        Memory at f0000000 (32-bit, non-prefetchable) [size=128M]

I patched the xorg driver source package that came with Ubuntu 8.04. For reference, the full patched source I used is available via SVN here:

This currently only works with 24 bit depth, tested with mplayer and totem. On 16 and 15 bit depth, mplayer repeatedly issues the following error:

  X11 error: BadAlloc (insufficient resources for operation)

and displays an image of constant color. Totem just exits when trying to play a movie on 15 or 16 bit.
