 > can you attach this to the PR too?
 
 OK.  I tried to attach the previous message, too, but I assume the
 system was unhappy with the 180KB+ log file.

 There is such a switch.  I have tried playing with it under FreeBSD,
 and got nowhere.  I don't seem to have to touch it under Ubuntu (or
 maybe I only had to use it once).

 Other than having FreeBSD try to use ACPI, I don't know anything about this.
 This appears in the boot log, and might be relevant:
 
 Feb 20 16:11:25 halfpint kernel: acpi0: <ACRSYS ACRPRDCT> on motherboard
 Feb 20 16:11:25 halfpint kernel: ACPI Error: Could not enable PowerButton event (20120215/evxfevnt-217)
 Feb 20 16:11:25 halfpint kernel: ACPI Warning: Could not enable fixed event 0x2 (20120215/evxface-575)
 Feb 20 16:11:25 halfpint kernel: acpi0: Power Button (fixed)
 Feb 20 16:11:25 halfpint kernel: acpi0: reservation of 3f800000, 70800000 (3) failed
 Feb 20 16:11:25 halfpint kernel: cpu0: <ACPI CPU> on acpi0
 Feb 20 16:11:25 halfpint kernel: cpu1: <ACPI CPU> on acpi0
 
 How do I find out if there is an ACPI module available, and if so, how to load
 and enable it?  When I got this netbook it had a dead hard disk (i.e. no software),
 and no useful documentation.  I have downloaded the available user and quick start
 guides from Acer but I don't see much useful info.
