This stuff has just been updated and tested on FreeBSD. 
Maybe NetBSD ACPI folks could share the code/ideas on that field if desirable.
I've a ThinkPad laptop with FreeBSD 6.0 on it an both suspend and battery status work fine.
Suspend there is done with ACPI: acpiconf -s 3 will suspend my laptop.
A sysctl switch - hw.acpi.do_powerstate=1 will turn on powersettings and hw.acpi.likd_switch_state=S3 will suspend my laptop when i close the screen.
