Mh, maybe add a comma after 'option=always'? You can also add
\enabletrackers[backend.pdfx]
in front of the \setupbackend command to get additional info in the log.
Is there a reason to force embedding of the profile? If I remember right
PDF/X-1a can do without, if the profile is common.
\setupbackend
[format=PDF/X-1a:2001,
intent=Coated FOGRA39 (ISO 12647-2:2004),
option=always, % for a much bigger document :-)
]
should be enough ('file' is derived from the entry in
colorprofiles.xml). A profile with this name should be in the specific
path. See
http://wiki.contextgarden.net/PDFX#ICC%20profiles
for the details. The mentioned $OSCOLORDIR variable is no longer valid.

Just guessing (your description rings a bell):
Use '\startoverprint ... \stopoverprint', not the global
'\setupcolors[overprint=yes]'. The latter is only useful, if your
document is pure black text only (everything in it is overprinted)!
