Hi Garrett,

I have decided to do that one machine at a time but for now I'm just  
going to keep all as is.  It seems to be working fine on both current  
and releng with the standard intel compilation.  I just ordered a new  
machine that I will setup with current amd64 for evaluation and then  
decide after I've actually used it.

Thanks to all for helping me get my feet back on the ground.

have a great weekend,
