Known problems:

  - If an "uppermem=" command was used to tell GRUB it had a different
    amount of upper memory available, then the user escapes to the menu
    interface, the upper memory displayed there still says the amount
    set by the user instead of being reset to the default by the escape.
    It actually resets when the next command-line is entered or config
    file entry is executed.

  - There is at least one problem when using an "install_partition" that is
    a BSD sub-partition where the PC partition isn't explicit (i.e.
    the default 0xFF00FF is a problem)...  this is when using "makeactive"
    without explicitly setting the root partition.  If this is done, a
    "no such partition" error will be generated.

  - Cannot boot FreeBSD "kzip"ed image.  Use a normal kernel (using GRUB's
    automatic "gzip" decompression works fine).

  - Hitting Ctrl-Alt-Delete when in GRUB locks some machines.  Use Reset
    for now.
