Come now it's not as far off topic as the guy who wanted a MacOS X 
terminal program.

I guess the 7300 is like the 7200 in that it doesn't have the CPU on 
a daughter card.  Before going crazy, have you looked to see if the 
MB has any vestiges of the plug for the daughter card in the traces? 
I might optimistically hope you just need to buy the right connector 
and solder it on (and desolder the original CPU).
