That's an excellent question. I got my configuration working using the
"trial and error" method of debugging. In my case (Intel 945GM), I was
successful using
Driver "vesa"
in my xorg.conf.
If your curious, 7.0 supports the Intel Integrated video chipsets
natively and the 915resolution port is unnecessary. Also, my stock
xorg.conf generated by Xorg -configure gave me 1680x1050 resolution.
Hope that helps...
