Here is some illustration of progress
1) Primer of offset table usage to call functions. This is very interesting part, as it allows to dump vram.

2) Second part shows part of shooting speed related procedure, here you can find how big structure is used. I believe that at 0x68 we have mode wheel position.

     Well done. Your effort has already generated impressive amount of useful information, as well it has been documented in accessible and ordered way. Unfortunately until there is some development environment and ready tools, your'e still at a stage that very specific knowledge and huge dedication to the task is needed to proceed. Because of the relatively small Pentax comunity there are probably just few so capable people as you are. BIg thanks and heads up! You should post more details on what people can do to help you in this site.

     There is a serious limitation with K20D, K-7 that makes bulb exposures extremely difficult and tedious. It involves mandatory noise reduction which doubles every exposure, if exposure time is longer then 30 second. I ask PENTAX if they plan a firmware upgrede to solve this problem, but the answer is NO. I must join you and try to hack noise reduction. How to start?

     Have you tried simply doing a multiple exposure in sets of 15 or thirty seconds for example you can do three multimple exposure os the smae iamge ona tripod at 30 secons each and that would be 90 seconds exposure with no noise reduction.
