ACPI puts all of the responsibility on the OS. With APM, the BIOS is
doing it all for you.
The reason you have this problem now is because the OS isn't doing
anything with that battery discharge info. That is what has to change.
It will be the same with "critical temp shutdown".
Windows is the same way -- the OS has to do EVERYTHING with ACPI.
However, this is actually a good thing, because you can define the
policy to whatever you want, as opposed to what the APM BIOS wants to
provide to you.
