What version of Lilypond do you use? I recommend that you 
install some version 1.4.x and try the example file
input/regression/note-head-style.ly.

In the reference manual, section "Sounds", the following bug is listed:

     It is currently not possible to use the percussion channel 
     (generally channel 10 of a MIDI file)

Setting the MIDI channel would be an simple change in the code, 
the problem is that you want a good way to specify the different
sounds on the percussion channel. I don't even know how standardized
it is.

You can explicitly specify the note line where the rests are 
typeset, see the example file input/regression/rest-ledger.ly.
