Thanks.

I already use a powerd script to handle the power button to do a shutdown. 
Do I need to disable that. I am unclear whether this means that powerd 
will also run the sleep_button script after my power_button script. Or I 
can just rewrite my power_button script to do something to suspend.

I also already use powerd script lid_switch to run "vbetool dpms on" to 
turn my display back on when released. Any sysctls I should also be using? 
(Sorry I just can't find any docs about this.)

Where is the machdep.sleep_state sysctl tunable documented?

Thanks for your info...
