I wandered back into the world of CHDK and found that STICK is now the "go to" option for loading CHDK onto Canon P&S cameras. Prior to this I used CardTricks, but it seems to be unsupported now, and I'm on a Linux system anyway so it's not really an option.
I've tried both ASSIST and STICK, but they don't seem to work with my SD300. As a side note, both work perfectly fine with my SD1000.
It seems like either program is not picking up the firmware version of the SD300, so I'm guessing they both don't believe there is an appropriate CHDK available for download. Using the ver.req file, I'm able to see this on my SD300:
P-ID: 30BF NT
Firmware: 1.00K
No errors

CHDK definitely supports the SD300 and this firmware version, and I've used CHDK in the past (<v.1.0):
http://mighty-hoernsche.de/bins/ixus40_sd300-100k-1.2.0-3456-full.zipI'm wondering if someone could shed some light on the issue? Here's the relevant info from ASSIST:
