I've got compiz and all on my lappy w/ intel 945 right now. The only
thing bad is that is supports a max of 2048x2048 virtual which makes
using it with Dual monitors less nice when my laptop is at 1400x1050.
p.s. ff scrolls justs fine -- it took more work to get my 5 button
scroll wheel mouse setup then video.
