Subject: [PATCH] fix IS_I9XX macro in i915 DRM driver

Now that we're mapping registers in the DRM driver at load time, the driver 
actually checks the PCI ID, so we need to make sure the macros have all the 
right bits (and longer term use the DRM headers as the sole copy of the PCI & 
register definitions).

This patch adds 945GME support to the DRM headers, fixing a regression 
reported in http://bugzilla.kernel.org/show_bug.cgi?id=10395.

Dave, please ack asap so this will be fixed in 2.6.25 proper.

Thanks,
Jesse
