Subject: [PATCH] Fix running in G4 mode

Hi Samuel !
I noticed that MOL .61 is always running in G3 mode (no altivec). I tracked
that down to a bug in molcpu loop for matching against the current PVR which
will always stop on entry 0.
MOL is running fine in G4 mode on my 7450 (I didn't try letting macos know
it's a 7450, I only expose a 7400 for now).
Here's a patch:
