Maybe just a typo but the ibooks used 750s; from IBM I think.
and if I got the summary table at
http://arstechnica.com/articles/paedia/cpu/ppc-2.ars/1
right, they all have 512 L2; at least dmesg of mine confirms that.

The question I have now: my box reports a "ki2c0 at obio0" and it has
a fan, but I never heard it run, even though the machine got quite hot
at times. Does it mean that there hides a fan somewhere behind that
interface and that it is currently uncontrolled and therefor always off?
