After the reverting of all changes http://git.linuxtv.org/cgit.cgi/media_tree.git/log/drivers/media/tuners/mxl5007t.c device now survives both, 'lsdvb' and rc kernels. Besides, despite all this, this device is already not working at its full potential. One of the tuners can withstand a few hours and then hangs. After that, in the application e.g. vlc is needed to select the second tuner and so continue to use the device. So this is actually a "single-seater" as Formula 1.
