    so I see :(

    The Matrox Meteor II driver I'm developing uses DMA memory, PCI shared
    memory, -or- reserve_bootmem memory in mmap(2), depending on card and
    system capabilities. It sure would be nice to have the vma there,
    especially now that I know about using nopage() for mmap, but it can be
    worked around...
