    Ok. With the latest version you sent I got it compiled and working. As far as I
    can tell from short tests it looks good (eth2 is tg3):

    CPU0
    0: 79344 XT-PIC timer
    1: 2428 XT-PIC keyboard
    2: 0 XT-PIC cascade
    5: 0 XT-PIC EMU10K1
    7: 81 XT-PIC HiSax
    9: 387286 XT-PIC aic7xxx, aic7xxx, eth0, eth1, eth2
    11: 75780 XT-PIC ide2, ide3
    12: 17740 XT-PIC PS/2 Mouse
    15: 2 XT-PIC ide1
    NMI: 0
    LOC: 0
    ERR: 0
    MIS: 0

    To make sure I will let it stress-test overnight and send you the results in
    about 15 hours from now on. If everything does fine I will redo with ide2,ide3
    on same interrupt, too. Just to see what happens with these Promise things...
