Hi,
I successfully added a pressure sensor to my Freerunner. The BMP085 chip from
Bosch Sensortec is a small (5x5x1.5mm) chip which includes a pressure and a
temperature sensor. Power and I2C is enough to get it working. I glued it next
to the BT antenna. The wiki page contains some pictures:

board/bmp085
