Thanks Brandon. Alas, the path used in the c_adc.c software just doesn't seem to exist in the Debian I'm using -- one of the big sources of confusion for me. I'm starting to think the only solution is to try to dig into the kernel source as Joshua suggests -- but that sounds like it might take more years than I have left :-)
