In particular, option ACPI_SLEEP=true was commented out in my default 
file. I've changed so many things before getting suspend to work that 
I'm not sure if that's necessary or not. But uncommenting that option 
isn't hurting right now, if nothing else.

Anyone out there can provide a road map of what happens on ubuntu dapper 
when, under gnome & gnome-power-manager, one tries to suspend (which 
scripts run). I always thought it was all about acpi and its events & 
scripts, but recently I've read that acpi checks to see if 
gnome-power-manager or kbatterymonitor (or some such) is running, and 
gives control to those for handling the suspend request. from there, 
gnome calls some hal scripts in /usr/share/hal/scripts, and I start to 
loose the trail.

While my system is suspending & hibernating correctly now, I would love 
to know how it's happening.
