Exact same issue appears on an HP EliteBook 8470p if you select "native UEFI"
as boot method in setup.  Legacy and hybrid boot options work fine.

Changing bug title since this is not a Mac-specific issue, although it is more
severe on Macs without the legacy/hybrid options easily accessible.

It seems that the driver either cannot rely on the AtomBIOS being accessible,
or we need to add code to enable the mapping with some PCI hacks?
