Perhaps this is the ultimate in persistence, but unfortunately is also
highly dependent on physical location in the machine (i.e. which PCI
slot even).

AFAIU, the "adapter0" is not representative of physical device
persistence but is rather dependent on probing order. IOW,
"dvb/adapter0/frontend0" will always be the first DVB device found but
won't be a guarantee of which physical device it is. This is what I
currently have with /dev/dvb/adapter{0.1} which is unfortunately
unsuitable since it's so predictable.
I might end up having to bite the bullet and using DEVNAME. :-(
Thanks for the info though, much appreciated,
b.
