    So, in addition to the patches from
    http://00f.net/blogs/index.php/2004/09/07/nvidia_kernel_module_and_linux_2_6_9_mm
      I've changed NV_REMAP_PAGE_RANGE to NV_REMAP_PFN_RANGE and
    remap_page_range to remap_pfn_range in nv-linux.h, nv.c, os-agp.c, and
    os-interface.c, the missing piece -- see below. I may get around to
    posting patches to the nvidia forum later today.

    I'm not sure if I can divulge the name of my helper in case he gets
    showered by unwanted email, but a suggested additional change to
    nv-linux.h has fixed it.
    #define NV_REMAP_PFN_RANGE(from, offset, x...) \
          remap_pfn_range(vma, from, ((offset)) >> PAGE_SHIFT), x)

    Regards
    Sid.
