Running the userspace power service, powerd(8), overrides the kernel's 
behaviour.

All the ACPI problems? Give me a break, we just finished a major rototill 
on a _development branch_ of NetBSD and had a ~1 week window where a small 
number of machines had issues.

Can you point to a specific issue that causes invalid shutdown 
notifications on -current that is caused by an ACPI problem?

I wouldn't trust a system that would rather trash my filesystem than 
gracefully shutdown when it detects a low power condition.
