I tried 2.6.19-rc6 and it works just like you said. Thank's a lot for 
the hint.
One problem left. I still can't set or unset the flag with echo even on 
2.6.19-rc6 (as root). Always getting a write error. Not that I care much 
about this, 'cause I for sure don't want it disabled.
But it's strange nonethless.

Thank's again
