IIC Maximum Speed?

In the data sheet for a 9S08GT32A it says in the "features" section that the IIC module can clock as high as 100KHz, and yet the control registers allow me to set the clock frequency as high as Fbus/20. I have several peripherals that have a max clock freq of 400KHz, and that's what I want to use. What's stopping me?

I see nothing in the AC Specs about the IIC module at all.
