G10

The Powershot G10 was released in 2008 with a 14.7 megapixel CCD sensor as the successor to the Powershot G9. It has since been replaced by the Powershot G11 and Powershot G12, which both have a smaller sensor resolution but better light sensitivity.

CHDK is available for the Powershot G10 with firmware version 1.02a, 1.03b and 1.04a from the Autobuild Server

Firmware info

As in other Canon PS case, the ver.req file works as well in this model. vers.req does the same job plus it reports the number of shots. Press FUNCSET and DISP simultaneously: It shows the following:

Canon  Powershot G10       
P-ID:318-F  PAL D       
Firmware Ver GM1.00F       
NoError

subsequent press of DISP (while still holding FUNCSET) reveals:

Adj. Ver.009.006
NoError
Aug 22 2008   10:55:13

and another press of DISP (while still holding FUNCSET) brings up this:

Adj. Ver.009.006

Official firmware update

In February 2009, Canon released a firmware update for the G10. You can find it (and description of what it does) here. It is labeled 1.0.2.0 and the camera reports version GM1.02A after the update. The firmware date is reported as "Dec 2 2008". The update is based on camera serial number but seems to apply to firmware releases 1.00F and 1.00H, converting them to 1.02A on the camera.

There may also be a physical mark on the battery cover of G10 cameras if the firmware was upgraded to 1.0.2.0 by Canon; details here.
