[PATCH] reduce useless changes on APM battery.remaining_time

[Danny Kukawka]

Hi,

this patch reduce change battery.remaining_time on APM every 2 seconds if the 
machine is discharging. The problem with /proc/apm is: nearly every poll 
return a new value for the remaining time. 

If there is a application using hal and listen to the change (of the property) 
ever two seconds, followed by do something via dbus (e.g. ask hal or 
powersaved for some information) this can result in a high load of dbus (see 
e.g. https://bugzilla.novell.com/show_bug.cgi?id=157905).

I changed the intervall to update the value of battery.remaining_time to 60 
seconds. This should avoid the problem, but should also be short enough to 
have always actual information in HAL.

Please review.

Cheers,

Danny
