    Having the kernel know how to manipulate MTRR's is useful for things
    like high performance I/O cards. Video is just one. However you definentily
    need MTRR's setting it is o.k. to do write back caching on your memory.

    I haven't looked. The fact that they are close probably means it is simple
    to convert the code if the code doesn't support your chip.
