reopening. The commit fixes the segfault, but xv is broken for me.

xv worked fine before this commit:
f170dddd3538a587f2363ef5fa10a4b484e762da evergreen: use vbo pool for constant
buffers

That commit introduced the segfault, the next commit fixes it but leaves xv in
a non-working state.

I'll attach a screenshot of a random video. There's usually one to three
colored lines at the top, and a huge rectangle at the bottom in a different
color. I suspect that the colours are parts from the video (based on the
frequency of change and the colours I got with different videos).

Audio works, seeking works and the "picture" scales correctly when resizing the
window or going fullscreen.

No messages appear in xorg.0.log, dmesg or mplayer's console output during
video playback.

None of these things changed anything:
- switching to mesa software rendering (LIBGL_ALWAYS_SOFTWARE=1)
- RenderAccel "on" / "off" (although the latter is needed to take uncorrupted
screenshots at the moment, will open another bug later)
- enabling or disabling kde 3's composition manager, kompmgr (xrender based)
- changing the window manager
- applying the patch attached by Matthew Cox

2.6.35-gentoo-r1 or -r6 on amd64 smp
X.Org X Server 1.7.7
HD 5770

Is there anything I can do to generate meaningful debug info?
