Sounds great ! What's average CPU usage at the moment ?

for me still no crunching with my HD3850 Cat 11.12 already set-up supposed that should be another problem except for driver some kind of ghost inside computer.
I'm starting to look strangely >:( to my box and some kind of "format .. " thought are coming to my brain :)
I'll wait for my NVidia GTS460 to be back repaired or new to decide start from the scratch.

Almost zero. For non-blanked APs its between 2-4 %.
(for bitcoin mining it's between 0-1%).

Meanwhile have tested this and it seems to be solved for single GPU :) , but NOT for multi-GPU hosts on 64 bit linux. CPU load with Cat 11.12 is around 80% when crunching MBv7r390_HD5 (Example: http://setiweb.ssl.berkeley.edu/beta/workunit.php?wuid=3710311 ) :(
Main problem solved : at least results done with Cat 11.12 are correct so far.

Sure is. Reintroduction of the old blocking synchronisation should help Raistmer, and OpenCL apps in general, a lot without having to redesign for new methods. Hopefully they didn't break the other mechanisms putting that one back ;) At least then there'll be options to choose from that work.
