Linux think my 8260 @200Mhz is doing 13 Mips ???!!?

hello,

 i have a strange question : our 8260 is clocked externally with 66Mhz
clock and is configured to have its core frequency at 200Mz.
But Linux is giving me this message when booting :

*****
Warning: real time clock seems stuck!
Calibrating delay loop... 13.15 BogoMIPS
******

       is that really 13 MIPS ?
       i hope the computation is wrong !!
       any idea ?


thanks,
Julien.
