    Can you make that an option ? The PPC version runs in real mode and
    can perfectly copy highmem pages (with small tweaks maybe)

    I also think we free too much memory btw (and spend too much time
    trying to free memory). Have you looked at some of Nigel stuffs in
    swsusp2 ? There may be good ideas to borrow...
