It turns out I was missing Henry Paulissen's patch, which can be found here: https://groups.google.com/d/topic/linux-sunxi/2a1p-zg24RQ/discussion and on sunxi-next. Now The interrupt on gpio-266 is firing, but never seems to stop.. at least with gpio-int-test.c. I will have a closer look soon(-ish).
