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:
If you want to use a wall fan control, you'll likely have to remove the remote fan control receiver from the unit. The remote receiver in the fan housing controls the fan speed, and will not allow the wall control to override it.
In the most basic case, the remote receiver will have "input" wires connected to the standard household wiring (ungrounded, grounded, grounding). The unit will then have "output" wires that connect to the fan, and/or light kit. Because of this, controlling the "input" of the remote receiver will have no effect on the "output".
The procedure for removing the remote receiver will completely depend on the unit.

The switch comes with the fan control you need. You have to replace the fancontrol from the fan with it. I'll include a pic highlighting the part I talking about.
