[PATCH] fix APM support and set/fix system.formfactor=laptop

[Danny Kukawka]

Hi,

this patch fix several things:

* fix detection of battery for APM: prevent to read battery info if there is 
no battery present. There is no battery if 'battery_percentage < 0' (and not 
'<= 0' ) or/and if battery_status flag is 0xff.
* fixed delete battery keys for APM if battery is removed

* Added detection of laptops to APM (if battery present) and ACPI (if battery 
bay or/and LID-Button) and set key system.formfactor=laptop

* fixed set system.formfactor from smbios.chassis.type to prevent overwrite 
otherwise set key (e.g. from APM/ACPI/PMU code).

Please review.

Cheers,

Danny
