UR right.  My figures were way off the mark.
The article was about Telia Net who run 1500 virtual suse sessions on a z 
series s390 with 12 processors.
The quote from the article actually reads:
"Even at the 25-30% physical server point it starts to make sense to 
virtualise on the mainframe, but the moment you start to talk about 100 
servers or more then the savings become substantial"

Apologies
