I dug up this thread
http://groups.google.com/group/comp.text.tex/browse_frm/thread/9b7cfaa205ed55b7/18dd46d6e5419170?lnk=gst&q=pdf%2Fa&rnum=1&hl=en#18dd46d6e5419170
which seems to suggest no, but I'm hoping something has changed since
then.
My university provides instructions for converting from .dvi/.ps to
pdf/a using Adobe Acrobat:

Are there any free tools to do this conversion?
