yes, it's something debian-specific thing;
the XFree86 is used, if you run startx or a display manager;

/usr/X11R6/bin/X: setuid setgid ELF 32-bit LSB executable, Intel 80386,
version 1 (SYSV), for GNU/Linux 2.2.0, dynamically linked (uses shared
libs), stripped
/usr/X11R6/bin/XFree86: ELF 32-bit LSB executable, Intel 80386, version
1 (SYSV), for GNU/Linux 2.2.0, dynamically linked (uses shared libs),
stripped

it's hard (and long job) to reproduce the problem and disabling the
mmap() base randomization helps me;
i'll do it, but not today;
