This is fine. I would also like to see the pci=norom option
added as-is with the thought that we may improve later by either
modifying pci=norom to exclude devices that need memory mapped
to their expansion ROMs or by adding another option (pci=minrom ?)
that would do the same thing.

Works for me. Thanks.
