Adding PMU and ACPI into HAL

[Richard Hughes]

Right, I've spent the last 2 hours looking at HAL code.

> 1. HAL detects ACPI/PMU and registers a new bus (like it would for PCI) 

How? It's never present in sysfs. I guess a hook is needed in osspec.c,
but where and what? coldplug? osspec_init?

A little bit of sample code would be fantastic.

I've started with ac_adaptor_class_device.c...

> 3. An addon is launched for the duration of the battery to update the
> battery charge level. (when the addon code hits CVS...)

Seems like a far away dream.... :-)
