    Thanks for the responses Jeremy and Randy.

    I tried taking the acpi dock patch seperately out of the mm patchset by
    applying this patch:

    it successfully is applied, and i notice that CONFIG_ACPI_DOCK needs to
    be set, so I did a "make oldconfig" after applying the patch, expecting
    it to ask me whether or not i wanted to support it... it didn't. So
    then I manually added "CONFIG_ACPI_DOCK=y" to the .config and built the
    kernel, but dock.o is never built... what else do i need to do?

    If i can't get hot swappable support yet, I might as well get what is
    supported for now so I can atleast use it sometimes :)

    Maybe this cry for help will spark someone to finish off the work on hot
    swapping the optical drive.
