Nonsense.  It's just not printed to the screen by default.

Because you're running a vintage kernel.  The 0 BogoMIPS bug was
introduced by this CVS change:

  revision 1.54
  date: 2005/02/21 21:34:24;  author: ralf;  state: Exp;  lines: +2 -2
  On multiprocessor systems the BogoMIPS for each CPU was reported was
  the value for the last CPU having calibrated it's delay loop.

Only the value shown in /proc/cpuinfo on UP kernel was affected, so the
effect should be purely psychologic - I know what negative impact low
BogoMIPS may have on some people ;-)
