All these 'override's can be 'final's.
...
At least for the purpose of being communicative. I doubt there's much to gain in terms of compiler output — the DiskImageHolder can avoid some virtual lookups but nothing else leaps out.

Logic being: name these things for the bus action they model, not the effect they have.

Withdraws requirement for DiskController users to specify a PLL multiplier or to provide rotation speed.

In the latter case because it's no longer of any interest to the controller, and in the former because I'd rather it be picked automatically.
