(i'm terribly sorry for butting in, but i'm in the same situation -
wanting to work on the power stuff that seems fairly important -)

same problem here. I've been mostly hacking and getting up to speed on
many different aspects, but lacking proper doc'n, am finding it
difficult to focus. And i called in to the power mgt telecon, but had to
catch a plane and had to disconnect after 20 minutes.

afaic, i wouldn't mind doing the mod myself - it sounds like it's an
unpopulated header, and my soldering skills - even smt - should be ok
for it, but there's no doc'n on it, and the schems are private.
i'll readily admit that i have less than 20hr/wk to give, but i'll also
admit i haven't been super productive on the hours i did give so far.
