Could it have to do with the computer going to sleep? I wonder if that's what 
the "power_save" means.

Anyhow, I had a lot of trouble initially with my PowerBook (again, a 3400c, 
not an iBook) with sleep, but now it works pretty well. For what it is worth, 
I will give you some ideas which helped with my machine, but may not work 
with yours since we're comparing apples and oranges (no pun intended ;)

The package which ordinariliy handles sleep in the Mac is "pmud". You might 
want to make sure you have that installed, or at least upgraded to the latest 
version:

   emerge pmud
   rc-update add default pmud

Second, do you dual boot? The reason I ask, is that for the 3400c at least, 
there are issues with the power saving software which is stored in the 
non-volatile RAM (a.k.a PRAM) of the computer. The way I understand it, that 
software is loaded by Mac OS and Linux does not know how to update it if it 
gets erased. So, if sleep acts flacky under Linux, a good solution is to boot 
into Mac OS once, and then go into the power saving control panel to give it 
a chance to refresh. For the PowerBook 3400c, there are specific instructions 
in the manual on how to force this power management software to be flushed 
and reloaded again. Doing so has solved a great deal of instability issues 
with my PowerBook.

Again, please take this advise with a grain of salt. These tricks worked for 
me on a 3400c using Mac OS 8.6. I'm pretty sure a lot has changed with your 
iBook, so I wouldn't try anything before researching it :)
