    I think you misunderstood what he wrote. Here's the relevant part:

    "...PowerMac G4 support including models PowerMac3,1 to PowerMac3,6 with the requirement of [...] at least a 500MHz cpu card. The cpu part is still a bit open since we don't have machines with < 1GHz G4 CPUs for testing really and there are some known problems for the original low end 350/400/450/466MHz cards found in PowerMac3,1 to PowerMac3,4"

    So it's seemingly not a matter of the type of MPC74xx (MPC7400 or MPC7410 or whatever) but a matter of the clocking, for whatever reason which pega-1 didn't explain. At least that's how I've understood his statement. In detail this would mean:

    PowerMac1,2 (MPC7400):
    - not supported: 350 and 400 MHz
    - supported: none

    PowerMac3,1 (MPC7400):
    - not supported: 350, 400 and 450 MHz
    - supported: 500 MHz

    PowerMac3,3 (MPC7400):
    - not supported: 400 and 450 MHz
    - supported: 500 MHz

    PowerMac3,4 (MPC7410):
    - not supported: 466 MHz
    - supported: 533 MHz (as well as MPC7450 at 667 and 733 MHz)

    PowerMac3,5 and PowerMac3,6 (MPC7450 and MPC7455(B)):
    - not supported: none
    - supported: all


    Thanks for that missing info Andreas, I've consolidated it into the OP.
