    I tracked the problem halfway down, with 2.6.20-rc1-ubuntu1 [1] it works
    and with 2.6.20-rc2-ubuntu2 [2] not.

    The diff is here, unfortunately the acpi changes are about 100kb.
    http://debian.christian-leber.de/2.2-3.4.patch

    (the problem is a bit different, it suspends, when trying to resume it
    goes back to suspend and when i try again it's dead)

    For some reason that i don't get vanilla 2.6.20-rc1 doesn't boot because
    ata_piix doesn't work "PCI: Unable to reserve I/O region...." no remote
    idea why it works with the ubuntu kernel.
    So i can't bisect it.
