20 Sorry for the delay but i didn't find the time to tests things before.
21 I can confirm, that vanilla-kernel +
22 grsecurity-2.1.7-2.6.14-200511060937.patch works.
23 In the meantime gentoo-hardened-2.6.14 was released with an ebuild which
24 also works. So the problems I had were fixed.
25 Thanks a lot.
