We offer a partial solution: First, use the add_pdb program (or better,
the addPDB action in parmed) to put the information from the original pdb
file into the prmtop file. Then, you can use addpdb with the -ext flag
to create a pdb file with the original information. Or, you can use the
outPDB action in parmed with the norenumber option.
This is a workable solution for a single snapshot; it is less helpful to
analyze an entire trajectory. (VMD doesn't know how to interpret the
"extra" in the prmtop file.
Others on the list may have their own workflows that address this problem.
