Cheapi2c monitors the i2c hardware lines on the card, so you get a raw dump of 
everything going over that bus. You have to work out which lines these are by 
yourself. IMO this is the easiest option (assuming you know which lines to 
attach to!).

Another option might be http://linuxtv.org/downloads/saa7146dump-0.1.zip
 This is a userspace dumper for the saa7146 PCI chips - it lets you dump the 
i2c registers and other stuff from usermode under windows. I'm not sure what 
architecture your card is. Perhaps it can be adapted? 

The final option is to disassemble the windows drivers.
