    What you're missing is the reason for modversions to exist - the fact that the
    kernel API *does* change between releases, and even within the same source tree
    (UP vs SMP builds, for instance). If we supported what you're suggesting, then
    the following *will* happen:

    1) Binary module for 2.6.N is released that uses an API that takes 5 parameters.
    2) 2.6.N+1 comes out, and said API has another parameter added (see the recent
    tweak-fest for elf_map() for an actual example).
    3) User loads old binary into kernel.
    4) Kernel OOPs when it dereferences the non-existent 6th parameter that wasn't
    passed by the un-updated binary.
