Yes.  MRTG stores the data in the RRD as retrieved from the Target definition, ignoring anything like Factor[], or the bits/perminute/perhour options.

The frontend should take note of the Factor[] and bits/perminute/perhour options, and do the necessary multiplication.

If you want MRTG to store the data in bits, then add ' * 8 ' to the end of the Target definition (spaces matter).  Of course you will then need to make sure that the labels and so on in the graph are set correctly, and remove the 'bits' option as it is no longer required.
