K20D Firmware Hack?

Currently mulling over splashing out on a K-5, but before I do so I want to get some more life out my K20D.

One of it's biggest pains is dark frame subtraction which can't be turned off (and I do a lot of 2 minute + exposures). Has there been a firmware hack released that can stop DFS from kicking in?

Awesome!!

Thank you so much for this!

I can confirm that it works on the K20D (v1.04). The only caveat is that you must leave the camera in debug mode in order to keep DFS off. Not really a major issue though.

Interestingly enough, I tried a 30 second exposure (without DFS) and it was noise-free at ISO 200 (actually impressive). Considering that, why couldn't Pentax just add the switch in the first place?
