You want a sparc on a card + power chips?  You must be high or something.
Most of the robot controller board I've seen are based on 8 or (less 
often) 16 bit microcontrollers.  These are designed to be small, low 
power stand alone computers with their own RAM and peripherals on-chip.

Good luck finding what you want.
