I don't think this is the solution. What if you have this new, fancy disk
the bios knows nothing about ? Scsi controller ? Firewire ?
Of course the bios has to know how to save the memory, but it doesn't have

You can't. The kernel cries about IRQ's being lost (judging from the
reports of other people)..
