Is there some good documentation on this?  I downloaded the SuSE
package, and couldn't figure out how to do what I want. 

I looked at apmd_proxy, but I don't see how to specify: "if power off
then standby instead".

It seems to me that apmd_proxy script is just doing whatever cleanup
might be necessary in the case of entering different modes, but not
changing mode altogether.

Is this correct?  

It seems that apm in the kernel is catching this event, and I have to
modify the kernel so it doesn't allow power-off and suspends instead.

Thanks,

Chris
