I would vote for making it work for standalone apps only. To make
ROMRAM Redboot work would mean moving the load point for RAM apps up
in memory for both RAM and ROMRAM RedBoots. This would waste RAM in
the ROM RedBoot case, and would give RAM apps less room in both cases.

Of course if we were clever, we could put in some CDL to make it
impossible to configure ROMRAM RedBoots.
