There's something odd in Xserver/hw/xfree86/drivers/ati/aticlock.c:
   {
         2, 255,   0, 1, 1,
        45,  45,   0,
         4, ATI264xTPostDividers,
       "Internal"
   },

NumD is set to 4, while ATI264xTPostDividers has 8 values:
             ATI264xTPostDividers[] = {1, 2, 4, 8, 3, 0, 6, 12};

Is there any reason for not using the 3,6 and 12 values ?

Yes. They are not supported by first-generation integrated Mach64's. For more recent chips, (a copy of) this field is set to 8 by ATIDSPPreInit().
