Random comments about FBInk usage ahead .

You should be able to use fbink_refresh() (or fbink_cls(), if you need a blank screen), f.g., for a flashing full-screen refresh:

        fbink_cfg.is_flashing = True
        FBInk.fbink_refresh(fbfd, 0, 0, 0, 0, FBInk.HWD_PASSTHROUGH, fbink_cfg)

Same thing for fbink_print_ot():

        FBInk.fbink_add_ot_font("PxPlus_IBM_VGA8.ttf", FBInk.FNT_BOLD)
        fbink_ot_cfg = ffi.new("FBInkOTConfig *")
        fbink_ot_cfg.margins.top = 500
        fbink_ot_cfg.margins.bottom = 600
        fbink_ot_cfg.margins.left = 400
        fbink_ot_cfg.margins.right = 50
        fbink_ot_cfg.size_pt = 10.0
        fbink_ot_cfg.is_formatted = True
        FBInk.fbink_print_ot(fbfd, "**Wheeeee!**", fbink_ot_cfg, fbink_cfg, ffi.NULL)
        FBInk.fbink_free_ot_fonts()

(Tested at the end of the try: block in the binding's hello.py example, which explains the indentation & variable names ).

In the same vein, I'm fairly sure you can send ioctl in straight Python, instead of relying on a C helper for the frontlight (I'd, err, forgotten you were doing Python when I originally mentioned a C helper ;p).
