You can easily test with Flex 4 SDK http://opensource.adobe.com/wiki/display/flexsdk/Setup+on+Linux

as3 code:

package {
 import flash.display.Sprite;

 public class Main extends Sprite {
 [Embed(source='test.fxg')]
 public var TestFXG:Class;
 public var testSprite:Sprite = new TestFXG();

    public function Main() {
  addChild(testSprite);
 }
}
