    I needed to rebase it against the current mainline (Makefile conflict).

    Some remarks:

    - It looks like arch/x86/kernel/acpi/wakeup.S is not necessary any more.

    - These warnings:

    /home/rafael/src/linux-2.6/arch/x86/kernel/acpi/sleep.c: In function ‘acpi_save_state_mem’:
    /home/rafael/src/linux-2.6/arch/x86/kernel/acpi/sleep.c:41: warning: initialization makes pointer from integer without a cast

    /home/rafael/src/linux-2.6/arch/x86/kernel/acpi/sleep.c:91: warning: ISO C90 forbids mixed declarations and code

    look pretty scary.

    - Could the real mode directory be called just "real-mode" or something like
    this ("rm" is not very meaningful :-))?

    Apart from the above and the _WAKEUP hacks mentioned elsewhere, it looks okay
    (from a very high orbit).

    Greetings,
    Rafael
