Is the SCSI device your main disk, or is it inessential?
I'm no guru, but if I had this error I would try the following:
(1) Try booting with "linux noprobe".
(2) Try adding scsi_adapter=off to /etc/modprobe.conf
(3) Try moving the aic7xxx entries from /lib/modules/<kernel version>
(3) Try booting with "linux pci=off"
(4) If the SCSI device is inessential, remove the SCSI card
If you get the machine to boot, I would re-compile the kernel,
perhaps with the SCSI driver in the kernel proper rather than a module.
