You are correct in presuming that mp:run-process does not have the 
capability to run a process on another processor.

While not necessarily of help to you on the Solbourne (yet!), Franz does 
market a multiprocessor Lisp, entitled Allegro CLiP (for Common Lisp in 
Parallel) that does allow the running of Lisp lightweight processes on 
different processors.  CLiP is based on the UC Berkeley dialect of SPUR 
Lisp, and comes with primitives for manipulating lightweight processes 
(LWP's), message-passing and signals between LWP's, as well as blocking 
and non-blocking locks.  CLiP also has macrolibraries for Multilisp and 
Qlisp, and thus has an implementation of futures.  Currently, CLiP is 
only available on the Sequent Symmetry (and, yes, it does use the shared 
memory to communicate between lgihtweight processes), but this could 
change given sufficient marketing impetus (read: vote now!).
