Glad it works for you! I was rather surprised at the lack of info in the 
man pages about this setup..  I even rechecked the FreeBSD 3.3 
amd/amd.conf man pages just now and they didn't list this option either, 
maybe I'm missing it. Not sure where I found the original config, must 
have been online at some point.


I suppose this quote from the amd(8) man page applies:
"A weird imagination is most useful to gain full advantage of all the 
features."
