just read this and that's good, but if all cards with eeprom detection
are affected, we have a problem.

I copy in what I had as reply for the previous mail so far.

>From the build date I expect the released 2.6.25. One could disable
tuner-simple and tda9885/6/7 support on customizing analog tuner support
on this kernel, but that is not the case.

Mauro did something to get the tuner type set earlier to avoid other
troubles, but this looks like setting the tuner from eeprom detection
fails now, since it is already set previously and a tuner callback with
the correct tuner from eeprom doesn't happen.

I can see something similar on saa7134 and a md7134. (card=12, tuner=38)
That tuner detection from eeprom was not 100% reliable since a while,
but only _sometimes_ a FMD1216ME was set instead the FM1216ME MK3.

Currently this will always fail on 2.6.25 if tuner=38 is not forced.

Since 2.6.25 tda9887 is out of the tuner module again, old tda9887 port
and qss options against the tuner module will make it fail to load too,
but this gives an error in dmesg, what is not the case here, just to
note it for others.

Gert, do we have more regressions for the WinFast 2000XP?

OT, but do you remember on which kernel your saa7134-empress worked
last? There are problems too and Frederic Cand reported a 2.6.9 working
or a snapshot around that time ported. That would be odd.

Cheers,
Hermann
