Well I just wanted to update you all -- I tried everyone's 
suggestions & wasn't able to solve the problem, so I went to the 
Apple store. The guy there told me to open up the case and press a 
little button next to the battery. He said if that didn't work, then 
probably the logic board had been damaged when the power came back 
on. Alas, pressing the button didn't work.

He wouldn't tell me how much it would cost to replace the logic 
board, and to top it off I got laid off right before the ice storm. I 
am hoping that either my homeowner's insurance or the surge protector 
company will cover the repair. In the meantime I've been just leaving 
it on all the time and it more or less works OK.

(I have no idea what all of that about Open Firmware means, I'm sure 
it would be very helpful if I understood it :)
