FWIW, the PowerPC Roadmap diagram on the Motorola web site does classify
their PowerPC line into generations labelled G1, G2, G3, G4, G5, and G6.
Each generation encompasses several different model numbers.  For example,
the "G3" family includes the MPC740, MPC750, and MPC755 as well as their
83xx embedded product line.
