MOL presents the CPU as a G3 (or G4 if AltiVec is available). That the 
real CPU is a 604 shouldn't matter. That OSX "requires" a G3 is because
the OSX doesn't support the hardware typically present in older systems
(not an factor when MOL is used though).

This is because module binary compatibility is affected by the
altivec setting of the kernel.

What MOL version are you using?
