I think he has been refuted by Shaykh 'Ubayd Al-Jaabiree: http://tinyurl.com/ybblq4d . I had to post the Cached version of the link since the original wasn't working. Excerpt from the post by brother abdulilah: "The sheikh [Shaykh Muhammad 'Abd Ul-Wahhab Al-Banna] had a set of tapes in his hands 1 of them was sheikh Obayd al Jabri's refutation of Aa'id al Qarni and the other three were from Sheikh Sultan 'Eed on the suicide bombings."
But, I don't know the contect of the refutation myself though.
