No. More than one VT can be on a head. I like the idea of VT pools per 
head. Why do I call it pools. Because I like to think of it expandable 
and shrinkable. Right now their is 32 VTs. With a multihead system you 
would have number of heads * 32 VTs. This can get quite expensive. So you
would start with one VT and if you VT switch grow a new VT. So teh VT pool
grows. Only one VT can be active per head.

I have though about that but have no answer. In a multihead system where
should printk go to. Any suggestion anyone ?
