According to this patch:
http://freebsd.rambler.ru/bsdmail/freebsd-arch_2005/msg00626.html
we need to clean up all CPU_ENABLE_SSE in kernel, as Ruslan said:
http://freebsd.rambler.ru/bsdmail/freebsd-arch_2005/msg00627.html
But we need working "options CPU_DISABLE_SSE", so I decided to replace
all "#ifdef CPU_ENABLE_SSE" to "#ifndef CPU_DISABLE_SSE" and
all "#if defined(CPU_ENABLE_SSE)" to "#if !defined(CPU_DISABLE_SSE)"
Also, #include "opt_cpu.h" was missing in sys/i386/i386/ptrace_machdep.c
After all this changes the reported problem is gone.
