With the new ebuild for the nvidia-180* driver I installed that
driver. Now disturtion of dvb-t broadcast has gone but still having
high system load (system processes). The beside kaffeine quiet system
gets about 50% system process load (sum of both CPUs).

I removed backingstore and triple buffering in beforehand.

Any ideas to decrease load?
