I think you have 2 options. First, you could try to update the BIOS. Newer
versions may support reserving more memory for video.
If that doesn't work, you could try using 855patch. It's a program
available at http://www.chzsoft.com.ar/855patch.html. Once you read the
instructions and download the program, you'll need to edit your xorg.conf
file:
by adding a line Load "dri" to the Section "Module"
by using the Driver "i810" in the Section "Device"
by setting VideoRam to the desired value in the Section "Device"
The first 2 lines, you already have. You'll just have to edit your VideoRam
setting to something larger than its current value of 8192.
Then, run the 855patch program before starting X. Then start X, and you
should be good to go.
To make the change permanent, you could call 855patch from an initscript,
but make sure it runs before X is started.
