Comment 23 for bug 981168

@Bilal, note that the i915 you're seeing in your lspci is the kernel driver, not the chipset family. For instance on my system it is:

$ lspci -vvnn
...
00:02.0 VGA compatible controller [0300]: Intel Corporation Mobile 945GSE Express Integrated Graphics Controller [8086:27ae] (rev
03) (prog-if 00 [VGA controller])
 Subsystem: Dell Device [1028:02f4]
        ....
 Kernel driver in use: i915
 Kernel modules: intelfb, i915

For some intel devices they don't give the chipset family, but you can look them up using the new xpci command:

$ xpci 8086:27ae
i945gme (8086:27ae|945GME) i945 xserver-xorg-video-intel
