Yes, please do if you can. I am guilty of not doing it myself over 
years. I'm sure people on this list can fill some gaps. Apart from 
examining dsme, its modules and dsmetest in initfs (and its runtime 
behaviour using strace), check also powerlaunch 
http://powerlaunch.garage.maemo.org/ It is replacement of mce (also 
closed). mce talks to dsme too and is done in similar modular way so it 
can help with some understanding. Powerlaunch imitates some mce<->dsme 
communication, see dsme.c,h at 
https://garage.maemo.org/plugins/scmsvn/viewcvs.php/trunk/powered/?root=powerlaunch

As for bme and figuring out how battery charging works, one could strace 
it and see what tahvo/retu register it uses, some bits are mentioned in 
kernel headers (not sure about name now, something like 
tahvo_retu_user.h) and there is also this info
