The fact that there isn't any information on the web about overclocking a 2400c doesn't mean it can't be done. The same applies to the resistor matrix on the 3400c.
On the 3400c, I'll bet you real money right now that the resistors you need to move around are R163 - R177. They reside beneath the PMU on the main logic board. In fact, maybe I'll take a crack at it and post my results on my webpage like I did the 5300...
Marc Schrier's page is always a good place to look for information on overclocking. http://homepage.mac.com/schrier/mhz.html I just looked, but I didn't find any information about the 2400c there. The 3400c overclock info that he has is about changing the bus speed, not the multiplier.
I've got what is purported to be a 2400c/240 prototype (actually, it appears to be a developer's seed model - it is a 240 MHz unit, but it is labeled as a 180 MHz unit, and it has the MacMedics and PowerBook Development Team stickers on the bottom). I haven't cracked it open yet. I'm actually a little intimidated by it - 2400cs are just so precious, and it took me years to find a 240 MHz model...
FWIW, I've learned to take Dan Palka's claims with a grain of salt. There were plenty of people before him who overclocked their PowerBooks (just see Marc Schrier's page for proof). What is more, he didn't take the time to buz out the resistor matrix. He could have had a far more impressive hack (a coup de grace if you will) if he had done the double whammy bus overclock and multiplier adjustment to squeak out max bus speeds and CPU speeds at the same time.
Peace,
Drew
