Thats one solution. My solution was to make redboot ROMRAM for my
target. It has the advantage you can update RedBoot as well. The
patches have not made it into the anoncvs yet though.

RAM/ROM?  Could you provide more details?  Use the same offsets, make it
PIC?
The issues of concern:
- RAM testing, during start, NO stack or shared SRAM, therefore all of the
handling of expectations was done without RAM. Just in case a fault
happened.  So, it is hard to make some of this bullet proof.
