I mean, if I call 'snooze -f' the iBook goes to sleep immediately,
just like under MacOS

	* display is turned off
	* hd spins down
	* network goes down
	* power led blinks slowly

The same happens if I comment out the contents of the 'sleep' case
for Core99.

This is on a regular Indigo iBook 366 Firewire

Kernel is 2.2.18 from ftp.kernel.org

I'm very interested in helping with power mangagement - if you need
something please ask.

Thanks for the info, I didn't know that... and no, I won't hold my neck out.

Whenever it sleeps I can't ping or otherwise access it. When it wakes
up the kernel prints the 'link state change ... link up...' lines.

Thanks lots for all the info!
