[issue1449] AHCI panic on Intel 6321ESB AHCI

    Hmm.  If the chip reset change didn't fix it... the CI register just
    could not possibly have a value of 0x00439cdb.  It's impossible.
    So it must not be mapped properly or in the right mode.

    Here is a new patch to try:

	fetch http://apollo.backplane.com/DFlyMisc/ahci09.patch

    This one plays some intel magic that may get the chipset into the
    correct operating mode.   I wish intel wouldn't play these games,
    AHCI is supposed to be AHCI, not some bastardized compatibility mode
    that requires screwing around with to make it AHCI.  The AE/HR sequence
    is supposed to do the job.
