    Interesting. I'd expect 25 myself ... then we'll definitely need

No; all devices on the same bus run at the same speed ... for per
device (well, per bus) we need a speed.

Actually, strictly speaking drivers should be able to handle the speed
changing at runtime too --- I'm not sure if anything does this right
now but it is permissible.
