It seems to works perfectly on some G7s, not at all on others. I would
suspect a firmware incompatibility. See the CHDK Wiki FAQ on how to
detect your camera's firmware version
http://scratchpad.wikia.com/wiki/CHDK/FAQ to see if this is what is
causing it.

It appears at this time that it may not be possible to port CHDK to
some other Canon Digic III cameras, specifically the S5 IS so far.
There may be others. Canon, in its corporate paranoia and insecurity,
has removed one of the menu features from its firmware which is
required to make this more easily possible. There may be some way to
do this in the future, it just hasn't been found yet. Effort to enable
CHDK on other Digic III cameras will probably be directed to those
models that haven't been crippled in this manner. This makes the S5 IS
an even less desirable camera to purchase. Some S5 IS owners are now
disappointedly returning theirs, having bought them with the
expectation that they too would eventually have all the huge benefits
of using CHDK.

It is interesting in that people are now deciding on which camera to
purchase, not by the camera's own capabilities, but if it can be used
with CHDK or not. The tail can most assuredly wag this dog.

It may not be too far of a stretch to think that future camera reviews
will have one more entry added to their features list: "CHDK
Compatible". Buyers skipping over those models that are listed as
"CHDK Denied". It may not be in camera review lists yet but it's
already happening.
