"Alternate water pump, alternator, power steering, and crankshaft pulleys of any diameter or material may be used."
...with no further restrictions. Thus, we invoke the Roffe Corollary. If you want to invoke the "prohibited function" clause that's easy: what's the intended function of alternate pulleys? To allow accessories to turn slower. Does a bearing-infused power steering pulley allow the power steering pump to turn slower? Yes it does.

Well, you're interpreting intent.
The allowance states nothing along those line. Altering diameter could increase speeds as well.
It allows any material, not any materialS, so it COULD be argued that a bearing design would be illegal if it used more than one material.
We need a devils advocate smiley.
