The answer has already been given, namely to use the method shown in 
the second example of 
http://lilypond.org/doc/v2.12/Documentation/user/lilypond/Common-notation-for-percussion#Percussion-staves
The trick is to use the standard <<{...} \\ {...}>> construct for 
polophony. If you use version 2.12 or earlier, you also have to 
explicitly instantiate two TabVoice contexts (just replace DrumVoice by 
TabVoice in the example) called "1" and "2" (these names are hard coded 
and cannot be changed). If you use version 2.13, there's no need to 
explicitly instantiate these TabVoice contexts, LilyPond will 
automatically do the right thing when it sees a << \\ >> construct.
