This looks dubious but with the right results.

The address passed back from the BIOS is a physical address. Not a bus
address, not an ISA address. phys_to_virt I suspect is genuinely the right

This slipped thru by accident, it is part of the "kill bus_to_virt"
stuff I'm working on with Jens. Oops...
