Gad. How about a hardware FIFO? How about a serial receive buffer on
your generic serial chip? I really doubt this rumour, unless some special
trick (like maybe modifying the actual instruction in the code cache
before the restart to skip the allready done part, yes, sorry, sick idea)
was to be done, it just has too many differences from the current 030
and 020/851 setup to be possible.
