I wasn't aware of mom.log, thanks! :-) After another host reboot 
and a manual "Sync MOM Policy" it seems like the setting finally came 
through:

2014-10-19 15:57:18,211 - mom.Controllers.KSM - INFO - Updating KSM configuration: pages_to_scan:64 run:0 sleep_millisecs:10

Now the ksmd process is still there, but it remains idle.
I've tried this multiple times before upgrading to 3.5.0 GA
today. Maybe it was broken between RC and GA.

I'll keep an eye on this and open a BZ in case the setting will
change again.
