(Bugzilla #1777) Import Mark Vojkovich's changes to NV driver since last

    sync with XFree86, including: Support for new NVIDIA chips. Egbert has
    a laptop that needs some DPMS ordering reversed. New chip support and
    workaround for Toshiba M30 laptop issue. PCI-Xpress chip support. DPMS
    support for DVI. Cursor changes for NV11 so that alpha blended cursors
    will work in conjunction with dithering (laptop panels). It previously
    did not. HW support for alpha blended stretch blits on NV5 and higher,
    though nothing is using them at this point. Add support for VBlank
    syncing the Xv Blit adaptor on hardware that supports it (NV11 and
    higher). Make console restoration a little more robust. We were making
    an assumption that failed on a newer laptop. Workaround for some NV31
    DVI artifacts.
Also add nVidia license statement to nv man page to comply with requirement
    that it appear in "user documentation"
