Are you sure about that?

I've got a .pdf here which lists:

Application: xdv2pdf
PDF Producer: Mac OS X 10.4.8 Quartz PDFContext

and text in it which is specced in CMYK is listed as such using  
Enfocus PitStop, including using the Eyedropper (which used to be  
freely available for Acrobat).

It does list the colourspace as ICC Based, but the colour (for the  
darkbluetype) is defined as:
Name: Generic CMYK Profile
Base: CMYK
Cyan: 100%   Yellow: 0%
Magenta: 70% Black: 25%

Relevant bits of the .tex file are:

\documentclass[dvips, 9pt, twoside, openany, twocolumn, showtrims] 

\newcommand{\darkbluetype}[1]{\special{color push}\special{color cmyk  
1 .7 0 .25}#1\special{color pop}}%c70y25
\newcommand{\processblacktype}[1]{\special{color push}\special{color  
cmyk 0 0 0 1}#1\special{color pop}}
\newcommand{\darkredtype}[1]{\special{color push}\special{color cmyk  
0 1 .65 .34}#1\special{color pop}}
\newcommand{\registrationColour}[1]{\special{color push}\special 
{color cmyk 1 1 1 1}#1\special{color pop}}%
\newcommand{\cmykwhite}[1]{\special{color push}\special{color cmyk 0  
0 0 0}#1\special{color pop}}%
