I don't see how the one follows from the other.  Just because its
CPU-facing interface looks like an ISA bus's doesn't necessarily mean
that there is anywhere, even internal to some chip, that actually has
ISA bus signals - and, in particular, it doesn't necessarily mean that
anything limits its speed to ISA bus speeds.
