I created a Si570 BreakOut Board with minimal configuration to have something that I can test and verify my BusPirate. I got the same results with the new board, the I2C Address Scan returns nothing.
I must have something wrong with my use of the BusPirate.
The Si570 BreakOut Board that I created is a little different than previously posted, it now will fit in a standard 600mil socket. Which means that it is a little bigger than the original 500mil config, but should be more useful.
Here are some of the build details.

You can almost see through the PCB material, the two sided image alignment is reasonable.
