I agree:  Doing so should theoretically fix the problem.

I see also an alternative way, which should ensure consistent 
checksums with less effort:

The fontinst script for mathptmx starts with:

\transformfont{ptmr8r} {\reencodefont{8r}{\fromafm{ptmr8a}}}
\transformfont{ptmri8r}{\reencodefont{8r}{\fromafm{ptmri8a}}}
\transformfont{psyro}  {\slantfont{167}{\fromafm{psyr}}}

Instead of creating ptmr8r, ptmri8r and psyr again from the
afm's, we could take the tfm's found under fonts/tfm/...,
convert them back to .pl, and use these.  This makes sure
that the faked math fonts always refer to the same "real" fonts
as TeX does.  

There is however a second problem which seems more serious 
to me:

I have examined the .vpl files generated from fontinst, and
I have found that there are no checksum entries for the "real" 
fonts they refer to.  (Well, that's just what Sebastian already 
said.) 

When I create a .vf from such a .vpl, my vptovf 1.4 does apparenty
either NOT add any checksum entries at all or adds wrong ones.
I can check this by running vftovp:

[E:\usr\wrk\fontinst\mathptmx1]vftovp zptmcm7t
This is VFtoVP, Version 1.2 [1d]

MAPFONT 0: psyr at 10pt
Check sum in VF file being replaced by TFM check sum
MAPFONT 1: ptmr8r at 10pt
Check sum in VF file being replaced by TFM check sum
MAPFONT 2: cmr10 at 10pt
Check sum in VF file being replaced by TFM check sum

When I run the resulting vpl through vptovf again, the
correct checksums are written to the vf.
  
Is this a problem with my vptovf 1.4 only?

Greetings

Walter
