6-phase stepper motors



Is anyone aware of a driver IC for a 6-phase stepper motor?  Similar to the SAA1027 but for 6-phases.  We've found some great little motors (minitaure, high torque, high speed etc.) but driving them manually from a processor is cumbersome - a dedicated chip would help.
 
Sorry we couldn't make it to the competition with our mouse, Blip-Squeak - hopefully we'll be there next year.  We will, however, be at the IEE Y2K Micromouse Grand Prix Final at Earl's Court on 1st July.
