Well, I might look at this from another way. In userspace we
have /sys/class/power/*/ to get information about the available batteries.
For one battery we want to immediately know when its charging state is
changing or might have changed (the other option would be to do even more
polling). And according to my understanding this is what the uevent file in
sysfs for the battery is for.
I have decided to follow andy's comment and will make mach-gta02 and bq27000
talk to each other to do this update. A patch should be on the way soon(tm).
