I think the cause for your different observation lies in the module load
order / configuration. Please check:
- Does your configuration set the card type manually (card=70 insmod option)?
- Does your configuration load the tuner manually?
There is the old problem that the tuner module MUST find the tuner during
its initialization, but its not visible until the driver switches the
bridge transparent. This makes the module load order important.
If you have some instruction that loads the tuner module, please remove it,
the saa7134 module will request it.
