The best solution may require informing the user space ntp code of
such events. This requires very likely modifications to ntp itself
(I may be wrong, I've not looked at NTP code for 5 years or so).

Doesn't the kernel send signals to init on suspend/resume
events, just like with power fail events?  You can hook on
that.

I don't think it does... at least not on powerbooks.
