    I guess the answer is a matter of perspective, given that DOSBox lacks an x86-to-PPC JIT compiler. You may want to have a look at those references:


    From there you can see that the x86 CPU that DOSBox emulates on your PowerBook should be performing somewhere between a 40 MHz 80386 and a 50 MHz 80486.

    I doubt it. DOSBox is a 2D application. Even 3D games running within DOSBox are rendered by the (emulated) CPU. I don't know if it's technically feasible to enhance DOSBox in a way that makes it possible for 3D software running within the guest system to have its graphics rendered by the hardware-acceleration infrastructure of the host system (like is possible with WinUAE for instance).
