Apply patch 3. Many of the fixes in patch 3 are obseleted by updates made to the FCL. So the FCL head is taken in preference. This leaves only the hack in the display channel implementation to do not do a screen rotation on syborg. That solution is a bit hacky, but actually revised in a later patch.
