 this problem still exists. the following lines are `vmstat` outputs from:
 
 hub.freebsd.org (7.3-STABLE):
 
  procs      memory      page                   disk   faults         cpu
  r b w     avm    fre   flt  re  pi  po    fr  sr mf0   in   sy   cs us sy id
  0 0 0   2383M  1856M   144   1   2   0   231  74   0  315   27   94 -62 -15 177
 
 kern.cp_time: 410252301 85725730 109247565 6553778 2886521518
 
 
 freefall.freebsd.org (8.1-PRERELEASE):
 
  procs      memory      page                    disks     faults         cpu
  r b w     avm    fre   flt  re  pi  po    fr  sr da0 pa0   in   sy   cs us sy id
  0 0 2   1036M   294M   561   0   0   0    37  46   0   0  498  700  683 -11 -14 125
 
 kern.cp_time: 100842337 28852004 161611939 12315794 2770482371
 
 the problem seems to be in percent() or cpustats() in vmstat.c.
 
 cheers.
