The files are there unofficially (that's why they're not included in  
the ff.dat file) and in an old version. You could try out the charmm27  
parameters with CMAP support by downloading the latest version of the  
source code in git master and use the latest files, which I can  
provide you with (send an e-mail to me and I'll give them to you). The  
CHARMM ff (for proteins and lipids at least) will be officially  
supported in upcoming Gromacs version 4.1.
