Left over from the old days (2.1) of the PReP port when
things were hard coded.  We used some of the space
between 0x80000000 and 0xc0000000 for mapping
IO devices in the kernel.

I thought all of this was now configurable in the
advanced options.  The configuration files should
set the default to remove this gap.
