I had the same problem even in intrepid with intel driver 2.4.0-1ubuntu1 and the Flabdablet workaround work for me. I also noticed that Depth 16 is not needed, but only the Modes line.
Would be nice to include this workaround in the ubuntu package or, even better, in the upstream driver (if it is not yet fixed in the already released 2.4.1: http://lists.freedesktop.org/archives/xorg/2008-August/038056.html which I'd like to test once is in ubuntu). If they are needed for further analysis I attach the Xorg.log before and after the workaround.
