The application is to mount a Plasma screen on its side. Which means the software simulation. We have tested on Windows and the i810 driver costs about 20% extra on a 2.4GHz P4 CPU to run portrait and play a movie. So it is possible to do reasonable cost. However using the ShadowBF under X the performance is, as you say, unsatisfactory. We have not found a portrait mode plasma screens yet, but that seems like the solution we need to look for, we do not want to use Windows.
