After doing so, you can convert your .CRW files into DNG files.
You can then use Lightroom or Photoshop Elements or CS3 to process your photos.
I have used this on an A570 IS, and supposedly it supports the G7.
Have fun,

"work on the G7's DIGIC III processor (and so the G9 too I presume)."
G9 shoots RAW and is supported by PS/Lightroom, etc. That's why its so popular
The firmware does much more than just allow RAW, it 'unlocks' wider control over shutter speed, aperture, exposure compensation, bracketing, also provides a battery meter (still missing from the G9 I think ?).
