Oddly, I found it and it was about a ceiling fan remote actually: http://arduino.cc/forum/index.php/topic,69960.0.html
The actual library is here: http://code.google.com/p/rc-switch/
Nevermind what they are saying about 433Mhz, the module takes care of that part. The software doesn't care. We are only dealing with serial bits.
To capture your codes using that library, instead of connecting the reciever module data pin to the arduino, connect up the DATA signal that is going into your transmitter module to the arduino.
As I mentioned, whatever goes out of the transmitter comes out of the receiver. So since you do not have a 350MHz receiver module (unless you wanted to take apart your ceiling fan and extract the module!), you can just pretend you do by connecting up to the transmitter output directly.
I hope that makes sense.
