What kind of initialization did you expect?  I believe
most SID components aim to start up in a state similar
to powerup of the physical devices.  However, since some
features of the hardware may not be emulated, and others
may be hidden by properties of the host I/O, you may get
away with using initial state on the simulator.

This is true in general with simulators: it is possible
to get a "false positive" in the sense that a program
may run on the sim but not on hardware.

Not really.  What you're seeing is probably a coincidence.
