You won't see anything on VGA because the machine's RAM is not working.
Which port did you use as a basis for a i965 port? i945? That one comes
pretty close, but needs a _lot_ of changes, still, before it would come
close to the point where you can start looking at enabling VGA..
If you want to experiment with supporting the i965 chipset, I suggest
you do the following:
* Get a i965 based desktop board first and get that running.
* Get an Artec LPC Dongle/FlexyICE and a Stuge LPC/PLCC converter.
* Get a USB debug device for console via USB
