Please re-read the section in the NR concerning explicit use of voices:
http://lilypond.org/doc/v2.16/Documentation/notation/multiple-voices. By doing
it this way:
\parallelMusic #'(ossia ornaments righthand lefthand pedal) {
s2. |
\voiceOne \tiny c''4\rest c8\rest^\pp \ottava #1 d'32[ a' d, a] \ottava #0
c,8\rest d32[ a' d, a] |
\voiceTwo r4 r4 <d' fis>4 |
s2. |
s2. |
}
Lilypond knows where to place the rests and there are no warnings about
collisions.

Here is a minimal (real) example of one measure that generates four warnings.
As you can see the rests in the third voice are simply invoked as "r4" while
the ones in the second voice are given explicit locations (which, again, I want
to do in this case). (I realize the notation convention here is a bit strange,
but the composer used these quasi-grace sorts of things to indicate his
ornamentation, but he also gave them full musical time values and rests and so
forth.)
\version "2.16.1"
\parallelMusic #'(ossia ornaments righthand lefthand pedal) {
s2. |
\tiny \stemUp c''4\rest c8\rest^\pp \ottava #1 d'32[ a' d, a] \ottava #0
c,8\rest d32[ a' d, a] |
r4 r4 <d' fis>4 |
s2. |
s2. |
}

I've looked at the link you shared Trevor, but the application to this issue
isn't necessarily obvious to me, other than that it makes me wonder if I need
to change the order I declare my voices in or something.

This construct implicitly assigns the properties of \voiceOne, \voiceTwo etc
in order to the several music expressions separated by \\. These settings
control the direction of stems, placement of rests, shifts to resolve
collisions,
etc. That is probably not what you want. This is all explained in
section 1.5.3 of the Notation Reference:
http://www.lilypond.org/doc/v2.17/Documentation/notation/multiple-voices#single_002dstaff-polyphony
The particular error message is probably related to the way
you are positioning the rests in ornamentsVoice, but you don't
say how you are doing that.
