how does one find out which firmware revision one is using? I am asking
as I have severe stability issues (the card works for a couple of hours
then at some point cold freezes the system). Note that with the other
budget card this setup works fine (uptime months...).

It could very well be a bad reception -> firmware crash -> card amok
problem... anyway I intended to use this card in dvb-t only mode and I
am on 2.6.22.1 and used the options saa7134 card=112 tuner=54
gpio_tracking=1 i2c_scan=1 as suggested in the wiki...

does this card work reliably for you (stable in a 24/7 vdr  setup?)

dmesg follows ...
