That's not a safe assumption, especially on platforms where there's no
BIOS (like ARM platforms).  Thankfully, for the platforms I care about,
the boot loaders I wrote for them _do_ do a full bus setup, so I don't
see a problem. :)

However, I have historially had the kernel over many years (probably
around 14 or 15 now) reassign all resources so that things are how the
kernel wants them, and not how my half-hearted attempt at setting them
up did (which only does a limited job enough to get the system to a
state where we can load the kernel.)
