AKA Poulsbo.
OK, forget I said anything.
You're utterly forked on that front; that hardware was/is a desaster, and Linux support is worse.
The few people who were interested in getting anything even close to 2D accelaration have given up years ago.
Your best bet is to find the best driver beta made ~10 years ago and a deliberately old Linux kernel and/or distro to use it on.
Or just try to run video without any accelaration at all.
