rum buildkernel breakeage

[Harald Schmalzbauer]

Hello,

I'm out of ideas: I have "nodevice rum" in my kernel, also 
WITHOUT_MODULES="rum linux" in my make.conf.
But some code still wants to touch rum which fails with the following:
...
linking kernel.debug
if_rum.o(.text+0x4e3): In function `rum_attach':
/FlashBSD/src/sys/dev/usb/if_rum.c:501: undefined reference to 
`ieee80211_ieee2mhz'

*** Error code 1

Thanks for hints,
