I had two boards with Intel 9xx Graphics, the Intel Double atom one D945...CFLthings2 and a Kontron (s479 mini itc board)
On the kontron, booted X with no problem but freaking slow compiz (3->15fps) and on the atom... no X...
needed to fix the atom setup adding to xorg.conf: Option "AccelMethod" "UXA"
And it had freakking fast performance: 50fps :)
I've done the same on the kontron and tada! Fast compiz back :)
Maybe not the issue but a fix: )
