Weird... one thing to note though: when waking, an iBook will often draw 
quite a large current, which then lowers down again, but the battery 
meter will sometimes get confused and report quite a low time-remining 
reading.. It happened a few times to me when running 10.2.3 (IIRC) and I 
got figures like 10mins when waking from sleep... it would then settle 
back down again to the couple of hours that I actually had remaining.

Still, I guess this thing happens when running beta software?! Just had 
a thought: have you tried swapping batteries with another iBook? You 
could then possibly narrow down the cause to either battery or iBook.
