There is a syscall which will load code to a slave processor and run it.
When Mark Brinicombe started this work, there were problems with the prototype
of the Hydra card he was using.
These problems are fixed now AFAIK, but I doubt Mark has had the time to do
more work on multiprocessing recently.
The RiscBSD FAQ claims that the Sparc 20 port is also working on

The Hydra card is plugged into the slot for the processor card which the Acorn
RiscPC uses as standard and which in turn allows up to six cards to be plugged
into the Hydra. I'm not sure if the card is available now.
