Important safety tip with USB and laptops: many (most?) BIOS implementations
don't properly configure the PIIX interrupt router and/or PCI addresses,
so really bizarre things will happen.

NetBSD's workaround is:

options         PCIBIOS                 # PCI BIOS support
options         PCIBIOSVERBOSE          # PCI BIOS verbose info
options         PCIBIOS_ADDR_FIXUP      # fixup PCI I/O addresses
options         PCIBIOS_BUS_FIXUP       # fixup PCI bus numbering
options         PCIBIOS_INTR_FIXUP      # fixup PCI interrupt routing
options         PCIBIOS_INTR_FIXUP_FORCE

Linux, as far as I can tell, doesn't have a way to do this.  Didn't work
with my laptop with 2.3.xx, anyway.
