For what it's worth, I had suspend/resume (ACPI S1 and S3) working on  
my Dell Latitude D600. -current doesn't provide a way to trigger a  
suspend, so here's the (old) patch I used:

	http://www.invisible.ca/~jmcneill/netbsd/d600/acpi-sleep-sysctl.patch

You can trigger a sleep with 'sysctl -w hw.acpi.sleepstate=<n>' where  
'n' is the ACPI sleepstate (1, 3, 4, etc).

There was a bug in the D600 firmware where resume would fail to re- 
initialize the display adapter if it entered S3 while undocked, but  
apart from that our ACPI suspend/resume code works flawlessly.  
Hopefully others have better luck on different hardware.

Good luck,
