See also Kafr al-Hanadwa and of course Finkelstein's own website, where there is a statement of support by noted Holocaust historian Raul Hilberg as well as an interesting interview on the 1967 war I recently listened to.
And of course, if you haven't already, read his books:
Image and Reality of the Israel-Palestine Conflict, New and Revised Edition
The Holocaust Industry: Reflections on the Exploitation of Jewish Suffering, New Edition 2nd Edition
Beyond Chutzpah: On the Misuse of Anti-Semitism and the Abuse of History
P.S. Can someone explain to me whether this means it is unlikely Finkelstein will be hired anywhere else? Can a campaign be organized for him to be hired elsewhere? Perhaps in the region, since Finkelstein is interested in the Israeli-Palestinian conflict...
