i855GM graphics documentation ?

[Olivier Galibert]

>From what I can read on Intel's website, this chip is an Extreme
Graphics 2 device, but I just can't find any documentation about how
to program it.  I've found the PRM for the i810, the i815 and the ICH6
audio, but the i855GM video seems unavailable.  Do people here know
whether it actually is unavailable or I've just been too dumb to be
able to find it?

  OG.
