As far as I know there is not yet a way the Crescendo can be made to  
work in Linux.
Also, knowing the right L2CR won't help since the kernel does not use  
the G3 CPU and so cannot set it's L2 cache.
In order to solve this problem the bootloader is the point that has to  
be patched as the kernel obviously is started with the 601 CPU active.
The bootloader seems to reactivate the 601 (or somehow deactivate the  
G3) before jumping into the kernel code.
One needs to find out at which point that happens and then find a  
workaround.

@Daniel:
As you are the expert in terms of miboot - what's your opinion?
