Comment 88 for bug 719620

viktor, yes, please open a new bug report for your issue (and report here the link), specially the regression can be different, unless if reverting the commit ac7729da880e742613129ee6dea0045328670d2d also works for you.

If you are not sure, just open the new report, and test the mainline kernels from http://kernel.ubuntu.com/~kernel-ppa/mainline/ . Pick the 2.6.32 versions and go up, since you say lucid works (it's based on 2.6.32), and detect in between which kernel versions things stopped to work, and report on the new bug.
