Trouble with "if_fxp.ko" kernel module ?

Hi Gary, 

I ran into this myself. 

From rom /usr/src/sys/i386/conf/GENERIC

# PCI Ethernet NICs that use the common MII bus controller code.
# NOTE: Be sure to keep the 'device miibus' line in order to use these
NICs!
device          miibus          # MII bus support
device          bfe             # Broadcom BCM440x 10/100 Ethernet
device          bge             # Broadcom BCM570xx Gigabit Ethernet
device          dc              # DEC/Intel 21143 and various workalikes
device          fxp             # Intel EtherExpress PRO/100B (82557,
82558)

It won't work without miibus.
