For those of you who don't know what CHDK is; it's a utility for some Canon Powershot camera that unleashes some extra features not available from Canon.
I was not aware of this utility. If it worked to enable RAW on Canon's new PowerShot S5 IS (which does not support RAW out of the box), then that camera would become MUCH more attractive as a carry-around model due to its tilt/swing rear LCD... That's a big reason I opted for the G9 is because RAW was re-enabled compared to the "crippled" non-RAW G6...
