display corruption with system crash with i945 and HD video.

[drag sidious]

I am using Debian Unstable with it's X.org stuff along with CVS/git
sources for i810_drv, i915_drm (and others), i915_dri drivers.

Followed this guide pretty much:
http://dri.freedesktop.org/wiki/Building

And for the intel drivers this:
http://wiki.x.org/wiki/IntelGraphicsDriver

Installed all of that in /usr/lib and whatnot. Only catch to get DRI
working was that I make a sym link
/usr/X11R6/lib/modules/dri/i915_dri.so -> /usr/lib/dri/i915_dri.so

To get dri enabled.

I have i915 in my /etc/modules so that the module gets loaded up at boot
up time.

My xorg configuration:

Section "Device"
        Identifier      "Intel i945"
        Driver          "i810"
        Option "LinearAlloc" "6144"
        VideoRam        131072
EndSection

And in my /var/log/Xorg.0.log I can tell the video ram is being
allocated..

cat /var/log/Xorg.0.log|grep kB

(II) I810(0): VESA VBE Total Mem: 7872 kB
(II) I810(0): detected 7932 kB stolen memory.
(II) I810(0): I830CheckAvailableMemory: 955388 kB available

Using 915resolution to allow my specific resolution
cat /etc/default/915resolution
#
# 915resolution default
#
# find free modes by  /usr/sbin/915resolution -l
# and set it to MODE
#
MODE=58
#
# and set resolutions for the mode.
#
XRESO=1280
YRESO=960
#
# We can also set the pixel mode.
# Please note that this is optional,
# you can also leave this value blank.

With INTEL_BATCH=1 enabled I get good performance with 3d acceleration.
40 fps on ppracer and 1700 or so fps with glxgears.(I only enable that
option right before launching games from a xterm)

With normal sized video playback using mplayer the xv and sdl stuff
works fine. Very fast.

However with HD-sized content I get a nasty crash. Screen corruption..
Nice psychotic moving plaid patterns. Audio fuzz. unresponsive keyboard,
no caps lock lights or mouse or anything. Total meltdown.

Specificly the only video I've tried is Elephants Dream. It's a full
length movie made entirely from Free software. Namely Blender3d (which
works great btw. Good work with the dri stuff)

But on the High-Def version of the movie it is what is causing my
problems. You can find it at:
http://orange.blender.org/

With the torrent it shouldn't take to long to download. There are a lot
of seeders. So you can try it out for yourself if you'd like.
AVI, MPEG4 (mp42) / AC3 5.1 Surround / HD 1920x1080

Playback works ok in Windowed mode.. Nice smooth playback. But when I
hit 'f' to go to fullscreen is when it crashes my machine. Experianced
the same problem with VLC and with mplayer -vo xv and -vo sdl drivers.
