I downloaded the refactoring driver from the bz2-link on this page:
http://linuxtv.org/hg/~endriss/v4l-dvb-av7110-refactoring and compiled them.

With the new driver I still got the error message :-(. But it looks 
slightly different than before: "saa7146 (1) saa7146_i2c_writeout [irq]:
timed out waiting for end of xfer". I presume the (1) is the second
registered frontend. Well this is my budget-ci card and not the FF-Card...

So I thought I might as well try your advice for the FF card for the 
budget card and changed the flag in budget-ci.c to SAA7146_I2C_SHORT_DELAY.
Now the error message that shows is: "saa7146_i2c_writeout [poll]: timed 
out waiting for end of xfer"

Until now I thought that the motherboard change had caused this problem, 
but at the same I have replace the S1400 with an S1500 with a CI 
connected to it.
I now have an Asus M2NPV-VM(NVidia GeForce 6150 + nForce 430) with an 
Athlon64 3200+ and 512MB DDR2 RAM(667).
I am running Debian Etch x86_64 with kernel 2.6.20+refactoring driver.
Maybe some of the above might give you a clue on what could be the cause 
of the problem.

Thank you for looking into the problem.

Have a nice weekend.
