Should I read out some of those specifications in software (if so, what 
software) or should I just get the card out and tell you all the numbers 
and stuff on it?

It's not going that fast, but over the last weeks, reception really 
seems to be getting a little worse - and it's not the dish. Reception on 
Windows is much better, but still not what it should be. I don't know if 
the reception is going backwards on Windows as well (it's been a while 
since I opened the Windows).

I've found different patches. I tried the most recent, posted by Simon 
Baxter on 29/07/2007 01:06 AM, it would be written by Mark Anderson. 
When trying to patch, I see this:

patching file drivers/media/dvb/dvb-core/dvb_ca_en50221.c
Hunk #1 FAILED at 721.
Hunk #2 FAILED at 757.
2 out of 2 hunks FAILED -- saving rejects to file 
drivers/media/dvb/dvb-core/dvb_ca_en50221.c.rej
patching file drivers/media/common/saa7146_i2c.c
Hunk #1 FAILED at 179.
Hunk #2 FAILED at 195.
Hunk #3 FAILED at 207.
Hunk #4 FAILED at 250.
4 out of 4 hunks FAILED -- saving rejects to file 
drivers/media/common/saa7146_i2c.c.rej

Do I have to try to apply them by hand? In cases like this, I prefer a 
complete file.. Thing is: the system really does not see the CI. dmesg 
says absolutely nothing, like the CI isn't there at all. No error, just 
totally nothing. I can physically disconnect the CI and report back 
exactly the same results. There is no ca0.

I don't want to pressurize you, that was not my intention. I know it's 
far from easy. I just had no idea where the current development was and 
wanted to know - when would anything for the S2-3200 come into hg, does 
the CI work, what's the stability ATM, I just had no idea. I just wanted 
to say I wouldn't need the S2 functionality yet. The latest files I have 
found appear to be from february, so I really had no idea.

And I'd like to say thank you, because it really is a lot of work, and 
not easy. Thank you, all developers and people who send in 
patches/drivers. Your work really is appreciated.

That's good news!
