I've been tinkering with a BGA-swapped CPU card and I've had difficulty getting it to run at speed because of the L3 cache ratio. The original 733MHz CPU works with a 4:1 ratio, but the 1400MHz chip needs 6:1. Does anyone know how to set the L3CR register at or before boot time? I suspect there is a way to do this in open firmware with a script of some sort.
Alternatively, is there a way to re-program the flash chip on the CPU card?
