As suggested, I reported the bug upstream. It is still present in kernel v3.4-rc7-precise and also in the latest drm-intel-experimental (http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-experimental/2012-05-14-precise/).
You can follow it from https://bugzilla.kernel.org/show_bug.cgi?id=43267
Sorry for the delay, but I have been quite busy recently and did not had the time to test the latest kernel versions until today (and didn't want to report without being sure the bug still was present upstream).
