Will Kinetis K64/K66 support a Gigabit PHY?

I'm planning to use either K64 or K66 with Ethernet, and in addition to the standard 10/100BaseT speeds, there is a chance that we may be asked to support a 1000BaseT Ethernet connection. Is there any reason why we can't connect a PHY which supports 1000BaseT to either K64 or K66? I recognize that the MCU itself may not be able to support processing large data transfers at those speeds, but as long as the PHY supports the MII interface and the speed, it will still connect at 1000BaseT if that is what the Ethernet switch supports, right? We're considering micrel KSZ* PHYs.

 

Thanks in advance,
