What's more, the replacement isn't a new firmware per se, but rather a patch which boots from the memory card and runs from the camera's RAM (apparently making use of the original firmware's functions), so you won't brick your camera.
I wonder, though, what the performance tradeoffs of using it is; I don't imagine that compact cameras would have large amounts of RAM to spare that can be loaded up with third-party software that they were never intended to run in production.
