I just submitted a pull request at GitHub for a fix I made to the klondike driver in cgminer.  It was incorrectly reporting the target fan speed on the status line (always 0% due to a math error).  Here is the diff if any of you adventurous souls out there want to try it out:

Now it looks like this (it's capped at 99% because there isn't room for a fourth character):

My question is this:  The firmware aways seems to be returning 255 or 100% for the fan target speed, even when the fan is obviously running slower.  Is there any current activity around this in the firmware?  Is the firmware source available for review?  And where are the firmware devs hanging out.  I wouldn't mind listening in or helping out.

Thanks,
