Let it be known that this reply is coming from someone who didn't even install his own empeg. However, the way I see it, for each device to work (light and fan), they each need a black, white, and tan connection. Since right now the single switch gives that black connection, can't you just run one black connection from one switch to the light and another black connection from the other switch to the fan?

Now you can use 2 different switches to supply black, white, and tan to the devices.

Or, this could burn your house down... but I doubt it.
