The interface-detection fails during boot -- long before anything in rc.conf 
comes into play. It used to say:

	sk0: <Marvell Semiconductor, Inc. Yukon> on skc0

It now says:

	skc0: unknown media type: 0x0

and the interface is no longer available (nor listed by `ifconfig -a'). This 
may be a hardware problem, but it used to work just fine before :-(

Thank you,
