Can you send me any details about the problems you have running the app in a 64b system. Is a compiling problem, or a problem executing the program. Please send the info about the problem to this debian bug, and I'll try to fix it asap.
BTW I contacted with the author, Cornel Ciocirlan, and he is developing for a new version, with Docsis 3.0 support. He said that he will relase this new version soon... I sent some patches and bugfixes for the new version.
