so we're all on the same wave length ;-)
since nut drivers (in fact, only newhidups) also expose such a
weirdness in HAL battery.technology (only "pbac" for the moment) as
the current hald-addon-hid-ups does...

2 side notes:
- the HID PDC (Power Devices Class) standard, used by UPSs, has been
partly designed with ACPI in mind, which explains why we have some
shared things between ACPI and [USB] HID UPSs.
- I try to give to you (HAL guys) some visibility on power devices,
other than ACPI, which might sometimes lead to confusion when
expressed in an unrelated thread. Mea culpa ;-)
If you prefer, I can keep these for my draft on that subject.
