I had exactly this issue at a well known British telecommunications company, I had a personality clash with my (newly promoted) manager and leaving was impossible because the manager did not want to see a diminished headcount. I manouevered myself out by working almost all of my time on some other manager's project and it got to the point where the argument that I may as well report to, and be appraised by this other manager was unarguable.
