kernel config for TiBook

[luis.sanjuan@hispalinux.es]

I was browsing without fixed directions ... and I found out two 
different kernel .config for tibook (benh tree):

http://ppckernel.org/configs/benh-powerbookG4
http://cattlegrid.net/~christophe/titanium/.config

This isn't an important issue, I think, but only for fun - I'm curious 
about some of these differences. Obviously many of them are self-explanatory.
No need to refer all of them. But, here is my full diff output only 
until "Networking options":
