Hampton Bay fan missing remote, replace with pull chain?
As far as I can find, having taken the fan down, there is no way to add a pull chain to this fan. There is also no remote receiver in any user serviceable area of the fan. The light housing connects to the fan body via a six pin Molex connector and contains a wattage limiter of some kind (per the Hampton Bay specs for similar fans).

I am unable to buy a replacement remote with a reverse button, nor have I been able to get the fan to reverse or speed up. The Home Depot staff were also unsure how to fix the problem, and the service personnel at the 1-800 number included with the fan remote were also unsure how to fix the problem.

The fan appears to be worth at most $70, so I am just going to replace it in its entirety. Lesson learned: avoid Hampton Bay remote controlled fans.

Edit: A look inside showed that the light housing was fubar (partially melted, probably killed the receiver). I replaced it with an aftermarket kit and voila:
