Ummm..  No.

Core2Duo is an INTEL chip. ( http://www.intel.com/core2duo/index.htm? 
iid=homepage+c2d )

In most Mac configurations, it is the Intel 64 bit architecture  
implementation.  The CoreDuo is NOT 64 bit however, nor is Mac OS X  
Tiger on x86.  Thus, any first generation iMac, Mac Mini, MacBook or  
MacBook Pro with a CoreDuo is not 64 bit, nor does the OS support  
64bit execution.  Only the 2nd generation Mac Intel hardware with the  
Core2Duo's sport the 64bit implementation, but even then, the  
operating system isn't truly 64 bit, and only supports a subset of 64  
bit operation through Intel libraries.  Not until Leopard will 64bit  
be really relevant on the Mac x86 platform.

The only place that 64bit Mac operation is valid is on the G5, where  
PPC64 *is* an option, however at this point in time, it would be a  
waste of time and effort to bother with it since the PPC is  
effectively a dead end on the Mac.
