I guess it's still the same company that manufactured the PA6T on behalf of P.A.Semi and which I mentioned 3 days ago. But there's a chance that they switched fabs. The Apple A4 is produced by Samsung for instance (A4 has (ex-)Intrinsity's/Samsung's Hummingbird core (enhanced ARM Cortex-A8 core) with on-chip peripherals probably designed by the former P.A.Semi team (except for the GPU)).

Last time I looked you had to acquire an architectural license from IBM to do that in a legal way.
