I can do, but I need an Ack from these guys:

POWER SUPPLY CLASS/SUBSYSTEM and DRIVERS
M:      Sebastian Reichel <sre@kernel.org>
M:      Dmitry Eremin-Solenikov <dbaryshkov@gmail.com>
M:      David Woodhouse <dwmw2@infradead.org>
L:      linux-pm at vger.kernel.org
T:      git git://git.infradead.org/battery-2.6.git
S:      Maintained
F:      include/linux/power_supply.h
F:      drivers/power/

... failing that, they should take it.
