Jerry, the i915 in the i915.modeset=0 kernel parameter is the name of
the kernel driver, not the chipset. I don't know the historical
reasons for it being named i915 (possibly it was only used for i915
and newer in the beginning), but at least nowadays it is used on all
chipsets, including i830, 845G, and 855GM. The DDX driver used to be
i810, even though it was used on i915 and i945 as well, but now it has
been renamed intel (this is the one packaged in
xserver-xorg-video-intel).
