I am currently testing a x86_64 machine with an Intel i945G chipset. The
intel-agp.c driver seems to work okay if I treat it as a i915G. (I can get
OpenGL to work with the DRI driver)
Is someone else (with documentation perhaps) looking into the newer Intel
chipsets, or is a patch like this okay?
Thanks,
Chris Wing
