Sounds like we have very similar problems - I have a LifeView twin usb 
tuner and a PCI WinFast 100T that I want to manage separately. Trouble 
is I can can't differentiate the USB twin tuners.

What I would suggest doing is dumping a udevinfo on the Nova adapters to 
two files and running a diff on them, i.e:

udevinfo -a -p $(udevinfo -q path -n /dev/dvb/adapter0/frontend0) > adaptor0
udevinfo -a -p $(udevinfo -q path -n /dev/dvb/adapter1/frontend0) > adaptor1

diff adaptor0 adaptor1

And see what comes up.

Unfortunately for me the only differences on my tuners changed on each 
boot :(

cheers,
