If the problem is only with a few platforms, my preference would be
to hardcode this to 64k or 0, and leave the platforms that require
something else out of the common zImage for now.

For all platforms that only need the 64k window and don't have any
of other special needs, I would also like to hardcode the virtual
address window eventually, so that inb/outb can still be a single
instruction.
