Ath0 802.11 comes up with Sam's patch but shows no carrier and I can't make it connect.

[eculp at cloudmaster.info]

On amd64 current I have installed the patch from Sam,  
http://people.freebsd.org/~sam/ath_hal-20080528.tgz, that seems to fix  
the hal problem but it still doesn't have carrier and a scan only gets  
"ifconfig: unable to get scan results"

I've even checked the handbook and it says basically what I've done.   
Any suggestions would be appreciated.

More information:

I don't have anything in the loader.conf.

I can't help be feel that I'm missing something here.  Thanks for any  
suggestions,
