Just for fun I reassembled a working program using the 90S8535 with
the Mega16 definitions. After changing a couple of lines that refer to
'ramend'
where the stack pointer starts off (0x45f in the m16 vs 0x25f  in the 8535),
the program worked well in the ICE200 and I would say that no change
would have been needed if a had a real m16 (the ICE has no ram past 0x25f
as it is only intended for the 8535, so the stack pointer doesn't work).

The interesting thing is that I did NOT get any warnings about rcall and
rjmp as
the program is still within the 8K boundaries. Is any part of your program 
straying into the upper 8k?
