Actually, I think having it output the states since boot would be more
consistent with other tools like iostat/vmstat/etc.  They report states
on the first iteration that are states since boot.  For example:

% iostat 1
       tty            ada0             ada1              cd0             cpu

Can you test this test patch to see if it gives you what you expect from
top -d1?
