ACPI and 4.9?

[Eric F Crist]

Hello List,

I have ACPI working on a desktop running 5.1 and everything works great.  If I 
press the power button, the system shutsdown correctly, the monitor shuts off 
after 30 minutes, etc.  I have a laptop that I'm not using 5.1, but 4.9 
instead (for reasons, see previous posts re: mouse).  According to the 
FreeBSD handbook, I can implement ACPI in 4.9 (rather than APM) by simply 
adding device acpi to the kernel configuration.  I tried this and get:

device acpi unknown

What should I do?  Please point me to the correct FM.  

TIA!
