    They don't - check_sysemu is used also in TT mode.

    PPC port is not maintained at the moment - there are some rumors of somebody
    reviving it, but nothing is certain.

    I saw that from someone else - I don't remember what was the problem, but it
    seemed to be some strange kind of .config. Make sure that CONFIG_DEBUG_INFO
    and CONFIG_FRAME_POINTER are both set (the second is the needed one, the
    first implies the second for UML).

    "make oldconfig ARCH=um" should fix such problems.
