>From scole_mail:
So here is a patch to get basic ski console output working.  The ski
simulator was decoding the wrong registers in ssccnputc() due to
automagically inlined ssc() which contains a "break" simulated system
call.

The ski loader "skiload" has almost exactly the same inline assembly
call for ssc(), but for whatever reason, (maybe ssc() and
ski_cons_putchar() are in different files?), the ssc() function didn't
get inlined and I/O worked fine.
