If you're running into this restriction here's a diff of changes for pyfirmata.py that worked for me. Tested with a Raspberry Pi running python 2.7 and a teensy 2.0++ with the StandardFirmata sketch from Arduino 1.0.1 (PWM tested only)
(Can't work out how to display this diff properly!)

What tests are needed to adopt this solution?
