Frantisek,

thanks for providing the package for OS2006, that is great news. I installed 
it and it did not break anything as far as I can tell. The only thing I am 
surprised is that the module is reported as cx3110x  by lsmod:

Nokia770-49:~# lsmod

dmesg seems to tell that the fixed driver is loaded:

Again, many thanks for providing the package.
