You learn something new every day. To answer the original
question:
The different percussion sounds with shorthand names and
definition of note heads are listed in ly/drumpitch.ly.
Different drum kits are listed in scm/midi.scm
An example of how to use these things is given in 
input/test/drums.ly.
(All assuming you have a recent Lilypond version.)
