I disagree. There are very valid reasons outside the control of the BIOS
why the memory or IO space might be disabled. That said, the correct
place to check this is the PCI bus -- iff the corresponding bars are
properly initialised, it should enable memory and/or IO decoding.
That would reduce a lot of redundant code in the drivers.
