Well, the problem seems to be in the freebsd's implementation of dtrace.
Can some dtrace-guru say whether it is possible to fix the problem
on freebsd-side in a reasonable time? Or is it due to missing pid-provider
(or something else...) and then it is worthwhile disable dtrace support
in xorg-server?
I will try to find some time tomorrow and test the latest CURRENT
on my system too.
