I hacked up a master cylinder cap and put an air fitting onto it, and used an air pressure regulator to send air into the system at 10 psi. Made sure the cap was sealed onto the MC.
It was a little sketchy... the pressure broke the plastic on one MC, but held on another.
Then, bleed by opening the bleeder screw and slowly pushing the pedal down. The presure forces the fluid out, and it can't draw air bubbles back in.
The result is a rock-hard pedal. I had also tried speed bleeders, regular bleeding, and vacuum bleeding, but none of they gave me the feel I wanted.
I got the idea from a car craft magazine where they were using DOT 5 fluid. Pressure bleeding was the only way they could get rid of the spongy feeling associated with silicone brake fluid.
