This is true. I surmised that either the issue was widespread and so it'd get
reported, or it was just me and probably self-inflicted ;)

I realise that if everyone thinks someone else will report it, it never gets
reported though.

I did some more reading about FreeBSD's wireless support just now, it looks
like maybe a missing 
device wlan
could be the issue, however I'll build a kernel with the broken config
tonight and posts boot info.

IIRC it's hal attach returned 6, and another error 3. I went looking for them
in sys/dev/ath/ath_hal/ah.h but couldn't work out what I was looking for
(Very new to kernel dev, in case you'd not guessed :] )

Thanks,

Rich
