Ahhhhh very interesting to know. I had thought I was cleaning up

Well I'm not too hot on kernel development, in particular I really don't 
understand the frontend stuff and also all the internal i2c communication 
bits! I've written i2c bit banging protocol stuff directly before but this is 
all too weird...

That said if its just delaying unloading dvb core stuff until ref count is 
zero (rather than directly unloading on unregister) then I'll have a go. I'll 
have to see what the T2 driver's strategy is. I'll take a look this W/E.
