All currently manufactured AMD parts are 3.5 volts if I'm not 
mistaken (contact www.amd.com and browse around).  IBM's line of
processors do not have floating point units the last time I looked.  
I think it is safe to say that ANY 100Mhz part is 3.5 volt.  There 
are some companies that take 3.5 volt parts and install them on a 
litlle circuit board with regulator that plugs into a 5V 486 socket.  
I don't know how good these are at running FreeBSD.  Does anyone out 
there have any idea?
