//bugs.freedesktop.org/show_bug.cgi?id=1985) attachment #1504
    (https://bugs.freedesktop.org/attachment.cgi?id=1504) sync to 12/08/04
    version of Nvidia driver from Mark Vojkovich, including these fixes
    since last sync: Fix some DAC/Graphics memory contention issues on
    newer NVIDIA chips (specifically, NV40). More PCI IDs. Also, I've had
    trouble getting some panels to work automagically so I expose an
    FPTweak option to let the user adjust a troublesome register.
