Thank you, thank you! Here is the Go version of black.c:

package main

import (
	"bitbucket.org/mischief/draw9"
	"fmt"
	"image"
	"log"
	"time"
)

func main() {
	disp, err := draw9.InitDraw(nil, "", "black")
	if err != nil {
		log.Fatal(err)
	}
	screen := disp.ScreenImage
	rect := screen.R
	black := disp.Black
	screen.Draw(rect, black, nil, image.ZP)
	disp.Flush()
	time.Sleep(5 * time.Second)
	disp.Close()
	fmt.Println("rectangle was", rect)
}

One minor issue: the window is white after the program exits. Text doesn’t show until I hit the up and down arrow keys.
