I'm generating PDFs using pdflatex. I have found that the pdfx LaTeX module allows to make the files PDF/X compliant, but I would like to make sure that the generated documents are indeed compliant. Acrobat Professional provides a "preflight" tool for that. Is there any free software that can do this check, too?

I am not aware of any free (as in beer) or Free (as in Liberty) software that can reliably validate any of the different PDF/X-* standards.
If you need to do it regularly, and if your business depends on it, you might need to use closed source payware.
If you only need to validate a few files, you may get away with using a tool like callas Software's pdfToolbox5 ( www.callassoftware.com ) and their time limited test/evaluation license (available for Windows and Mac OSX in desktop GUI shape, and as a CLI tool for Linux/Solaris as well....).
