By the way, TeX itself does nothing with the checksum other 
than copy it to the DVI file. For checking whether TFM files
are set up for the correct encoding, it is handy to make
fontdimen 0 be the checksum so you can interrogate it
from inside TeX... Non-standard of course, but turned off
by the -K (Knuth) flag that kills all such extensions...
