The ARM6 and up is both, and in the ARM610/710 this can be set in
software by using a couple of co-processor instructions. I do not
remember which ones, but they are documented in the data sheets
from ARM, GPS or VLSI.

I agree with you here. The floppy drive on the Amiga is controlled
by one of the custom chips, and it is using 11 sectors per track.
I do not know if the controller used in the Risc PC will handle this.
