    Thank you for the message, Rusty. It's "fixed" already in battery2-2.6.git.

    Yes, battery/external power separation was a complicated part of whole
    battery stuff. Now, thanks to David Woodhouse, external power and
    battery classes merged, and there is much simpler configuration now:

    * Power supply class support
    Power supply class support (POWER_SUPPLY) [N/m/y/?] (NEW) m
    Power supply debug (POWER_SUPPLY_DEBUG) [N/y/?] (NEW) y
    Generic PDA/phone power driver (PDA_POWER) [N/m/?] (NEW) m
    DS2760 battery driver (HP iPAQ & others) (BATTERY_DS2760) [N/m/?] (NEW) m
    One Laptop Per Child battery (BATTERY_OLPC) [N/m/?] (NEW) m

    That's all you have to answer.
