The 2400 uses DRAM.  The iBook uses SDRAM (synchronous dynamic random 
access memory).  It uses different access methods.  I believe the 
2400 uses FPM DRAM at 60ns or faster, whereas the iBook uses SDRAM at 
either 66 or 100MHz (depending on model).  This comes out to like 7ns 
or something, but its a completely different kind of chip.  It's like 
why you can't plug a PCI card into a NuBus slot.

It seems like you're trying to max this out, and theres a lister from 
Japan that's digging up the 96MB modules.  Not certain, but I think 
he's asking $270 for them.
