I'm not up to speed with the latest Smoothie developments, the best place to get advice for anything Smoothie related is their IRC channel : [smoothieware.org]
I believe that the Smoothie on a breadboard should still work, but may be a little out of date. Smoothieware continues to evolve, and support for the breadboard option may need updating. I think in principle Smoothieware should be able to support 6 drivers, I don't know if that requires some modification to the code.
I don't want to dissuade you from doing a breadboard version, but I have a prototype board designed to run Smoothieware with RAMPS-FD, which would give you 6 steppers and 8825 compatible. There are not quite enough pins on the LPCXpresso for RAMPS-FD, my long term goal is to create a LPC1769 base board.
I've had little time to do much with it apart from run a "blinky" code, so if anyone is interested in helping with hardware/software development, I have spare PCBs or could make assembled boards available. It's mostly untested, so you would need some experience with low-level stuff.
