I decided to give up on Angstrom and move to Debian using Robert C. Nelson's images/scripts. On kernel 3.13, I'm able to access this driver and read temperature and humidity. However, the temperature reading is at least 10F too high. I don't have another calibrated humidity sensor to compare this against. I've kept the pull-up resistors onboard (i.e. I haven't desoldered them). Could that be the problem?
