It's not very difficult to support all PowerPC models, since at the 
instruction level there's little difference (at least for "normal" 
programs, for OS'es there are significant differences for some things). 
Only on the G4 you have the extra AltiVec stuff, but that won't be 
immediately supported anyway.

It'd be very nice if you could start testing the RTL support routines 
I've already wirtten for PowerPC (see in the PowerPC subdirectory of 
<>). Simply throw the 
body of the code in a C assembler function and you should be able to 
test them.

I'm mainly interested in Darwin, since I use almost exclusively Mac OS X 
nowadays. Since Darwin was partly derived from MkLinux, it may  be not 
too difficult to support MkLinux as well. There's also a bunch of people 
who want to do a classic Mac OS port already. I definitely intend to 
support different calling conventions from the start (they're different 
for LinuxPPC and Mac OS, and Mac OS X is again slightly different I've 
heard, even though it's derived from the classic Mac OS's calling
