Yep, but better use something like

%define __NR_chdir               12

to make code more readable. Also, your example works just fine here:

$ nasm a.asm -f elf
$ gcc a.o -o a -nostdlib
$ strace ./a
execve("./a", ["./a"], [/* 30 vars */]) = 0
chdir("/bin")                           = 0
_exit(0)                                = ?

Remember that chdir affects only the process that calls chdir. You
can't e.g. write a replacement for shell's builtin "cd" command that
way.

best regards,
