Actually, this info is what sparked (or is it 'Sparced'?) my interest last 
year.  However, the 20D11 is completely different internally than what the 
www.reputable.com info details, and so I had to devise my own mod.

As Mike Hebel requested, I'll try to put together some info with pictures 
this weekend. I just happen to have a digital camera on "loan" from work, 
though the picture quality is not so great...
