You should never ever consider something of this sort. You are inviting 
trouble. Should you do so, use mem= parameter to restrict the 
addressible memory in the board. then use the memory which is not 
addressible in the board as PCI addressible memory from the other computer.
I think you might require some non-transparent bridge in between if the 
board cpu is not configured in option mode. You might require some chips 
to do the address translation as well.

HTH.
