I think so, if you work with pdbs I think it only uses the first 3
letters of residue names. (but .gro files support the longer
names...). The file that Bert de Groot posted a few weeks ago will
have what you want won't it?

The script can take some options (near the top there's a line that
says # usage make_hole.pl -f 128popw_eq.pdb ... , that gives an
example; I don't know why I didn't just give the script a -h option 
to print that). 

Anyway sounds like you need to say 
make_hole.pl -lipid DMP -f ... and
possibly add also -lipat [something] if the phosphorous isn't called

Not that I know of -- it has to come through years of painful
experience and gigabytes of trajectories containing gibberish. Perhaps
the if there was sufficient demand combined with offers of money the
authors would consider it.
