Hm. I'm getting older, it seems. Now can anybody remind me why
pda_power.c doesn't work here? ;-)

This driver looks like a light-weigh version of pda_power, except
that it can do GPIOs directly (instead of is_*_online() callbacks).

Can we instead improve pda_power? Like this:

	if (!pdata->is_ac_online && pdata->ac_monitor_gpio)
		pdata->is_ac_online = pda_ac_monitor_gpio;

Should look quite cool, I think.

(Plus, we might get rid of ac/usb stuff in that driver, and 
pass enum power_supply_type to the callbacks instead).
