 Thank you christos, but I want to know why NetBSD don't prepare
 /dev/apm1 or /dev/apmctl1, like another device.

 Don't know, I'll have to take a look. This device is special, because
 there can be only one in the system. I don't think it makes sense to
 have apm1 etc...

 make this one "apm*" as well and see what happens.

 if configure my kernel as:

 apm*   at mainbus0                     # Advanced power management
 acpi0           at mainbus0
 apm*            at acpi?                # ACPI apm emulation

 then, 

 acpi0 at mainbus0: Intel ACPICA 20080321
 apm0 at acpi0: Power Management spec V1.2

 and apmd is started.

 # but, I have another problem,
 # 1. if suspend, lcd backlight is not turned off.
 # 2. after resume, wm0 and auich0 cannot work.
 # I use ThinkPad X31 (M/T 2672).
