Heh, well, if you can actually get full on 65832 compatable chip going, you
can count me in for a few. The only catch I can see is that you have to
implement 65C02, 65C816 and then 65832....

IIRC, the 65816 instruction set reserves an opcode for the 65832, so I 
presume the chip doesn't actually have a 32bit mode switch, but rather just
behaves 32 bit like when an instruction comes along that has the reserved
opcode as the first byte of it's instruction.
