Maxim also makes a driver, MAX7229 which provides a serial interface. - Tom

Each drives 32 ('52) or 33 ('53) segments with a common backplane. Doesn't matter at all how the segments are arranged (other than in your software). You might also check around on the National and Motorola sites for more. Several of these will do the trick. You can get a sample to drive a 4-digit 7-segment from my LCD-422 PDF (ask for a copy).
