Just tried to do the same and after some fiddling it worked.
I used this settings for the profile (slightly modified)

<profile>
        <filename>PSO_Uncoated_ISO12647_eci.icc</filename>
        <colorspace>CMYK</colorspace>
        <class>prtr</class>
        <id>Fogra47L</id>
        <info>PSO Uncoated ISO12647 (ECI)</info>
        <checksum>ae81087e1c54c6fdda2f93bd2d47cfaf</checksum>
        <version>2000000</version>
        <url>http://www.eci.org</url>
        <outputcondition>Commercial and specialty offset, paper type 4,
uncoated white paper, positive plates, tone value increase curves C
(CMY) and D (K), white backing.
        </outputcondition>
    </profile>


Copy the icc-profile into the same folder as the shipped profiles. Call
"context --make" to make a new format, update the file database.


%----------------------
\enabletrackers[backend.pdfx]

\setupbackend[
   format=PDF/X-3:2003,
   intent={PSO Uncoated ISO12647 (ECI)},
   ]

\setupcolors[cmyk=yes,rgb=no]

\nopdfcompression
\starttext
foo
\stoptext
%-----------------------

The produced PDF has a size of 1.7MB. Tested with
