I have a sugestion that may or may not work, but here it is.
If you have power at the first switch, with a 3-wire (black, white, red, and bare ground)going out to the light-- you can get a fan/light combo controler and have the red wire control the light and black wire control the fan, with the white as a common and the ground as ground. This will make the second switch useless, so if you need the light to come on in two places it won't work. If this will work for you, make sure you disconnect the other 3-wire in the light box that goes to the second switch.
