According to gdkmouse-fb.c, gtk+ for linux-fb tries to
handle mouse devices by itself, without any wrappers,
like this:

static gboolean
gdk_fb_mouse_ps2_open (GdkFBMouse *mouse)
{
  gint fd;
  guchar buf[7];
  int i = 0;

  fd = gdk_fb_mouse_dev_open ("/dev/psaux", O_RDWR);
  if (fd < 0)
    return FALSE;

Therefore, even if DirectFB works correctly on your target
system, the problem won't be fixed, I'm afraid. I will lookup
methods to use gtk+ for linux-fb without mouse device (but
I cannot answer within a few days).
