Btw, what is the best but 100% not-braking-anything config? That will work even with Xfree, OpenGL, etc stuff, so it allows non-grsecurity-kernel users to smoothly try a bit grsecurity?

that's a vanilla kernel bug, the two structures in question are defined after the arrays of them are, that could not have possibly compiled before either. it seems that 2.6.13 fixes it though.

that's what softmode was made for: you compile in softmode support then enable it on the kernel command line so that apps won't get protected by default, only those that you explicitly set up via paxctl.

So with exacly 2.6.x kernel and with (here to download) grSec patch should I use?

well, you can fix 2.6.11 by moving a few lines of code, or you can wait for the 2.6.13-grsec release. right now it's in the testing phase and there're some bugs to be resolved (check the forums for more info), so you should not use it for production.
