I can confirm that I initially built the sources with the DVB kernel headers in the wrong place and the build file seems to ignore the relevant modules and compile cleanly.  Nice touch - however, I suspect this is one warning message which will go unnoticed and lead to support calls like "why doesn't my DVB card do anything..."
