[NTLK] Changing the SA-110 Core Clock Frequency

I was looking through some of Apples docs and some docs on the Intel
 website for the SA-110 processor, The information indicates that
 there is a 4 line matrix that controls the Core clock frequency.
In the Newton, they have two of those lines already set and a
 surface mount resistor at either of the other two lines sets
 the core clock at either 100 or 160 MHZ. From what I was reading
 other combinations could produce speeds up to 233Mhz

I wondering if someone knows what Pins those 4 lines are on, and if
 there is a printed matrix table to program other speeds? If there
 were It could be possible to change the core clock without
 changing the bus speed and effecting the IrDa and sound functions
 of the newton.

Thanks
