Yeah, but why would I want to? If you connect your MAC to any 5 PHYs 
my statement still stands, if directly to MII you don't need any PHY 
stuff at all, because link is always ON and speed/duplex is fixed.

In fact, we use different switch chips connected to PPC4xx directly. 
In this situation, in my NAPI IBM EMAC driver I just have special 
"PHY-less" case which is trivial "fixed settings" one. And all this 
PHY lib is completely unneeded bloat.
