Ok, so indeed the commit is at fault, and situation didn't changed on latest kernel on natty. This X/Unity behaviour should be another issue, no problem about that.
I looked already at the commit we found in the bisect to cause the regression and at the code alreay, so far I didn't found anything yet, and will have to make a debugging patch and new kernel build with it for you to check, when it is ready I'll ask for more testing.
