There's also a pretty well-tested 6809 core around called "System09", 
for those who'd like to stick with a nice assembly language they know 
for like 30 years. Personally, when it comes to assembly language I just 
love 6809 and would prefer it over anything else.

Also, an AVR-clone is available at OpenCores in case you want to stick 
with a rather wide-spread 8-bit RISC architecture which also has good 
GCC support and a rather nice assembly language. (We're currently using 
that AVR clone in our "Multicore Technology" lab course for CS master 
students together with Spartan 3A 1800 DSP boards.)

Having not looked at that very 16-bit RISC: is there a GCC/binutils port 
for it?
