NO.  The whole point of hiding information in the checksum
rather than elsewhere in the TFM file is that the checksum is
COPIED into the DVI file and hence accessible to the DVI driver!

And yes, AFMtoTFM *also* uses the header fields to record 
some information in human readable form so you can just read
a TFM file into a text editor and see what encoding was used.

But that is not nearly as useful.
