I've used the psim BSP to pass data via shared memory with a Linux
application.  I added shared memory and semaphore devices to 
psim in order to do this and they are included in the standard
powerpc-rtems-gdb RPMs. 

As I recall, the UNIX port uses shared memory for the mptests so
it also has support for accessing shared memory.  Same trick
is already in place there.
