OK, I did it.
1. new libraries to /usr/lib64 and /home/boinc/boinc also /home/boinc/boinc/projects/setiathome.berkeley.edu
2. ldconfig (and fix few sibolic links)
3. stop X (should be done as step 0, of course)
4. install new nvidia driver
5. startx
6. start boinc
Works - let me see, if it validates. But mostly, if it works then it validates.
cuda task is taking some 10% of one CPU with GTX 260 and Q6600.
Thanks,

partially old/partial new: validated.
