Yeah - the card won't be initialised at all until you load one of those - the 
saa7146 support is more like a set of library functions.

For a budget card, only a couple of demodulators need firmware - the saa7146 
does not.

Hopefully michael's patch should stop the having to unload-reload thing... 
although you could try putting an msleep() just after the reset to see if it 
helps in the meantime...
