HP dc7700 video

Has anyone been able to use the Intel Q965 with DVI card as a dual head
xinerama or independent display? If so, what is the trick? I've tried
(using sax2) and the dual head setup doesn't get the monitors in anything
but clone mode. Manually configuring xorg.conf as two graphics cards seems
to work, but I get parse errors when starting X.
