Log Message:	Fix DGA mode for emulated PPC targets. It currently doesn't work in native mode as the stack is corrupted and we are jumping to garbage when moving the mouse. Also add 1152x768 resolution from PBG4, but make timing match the 1152x870 version. Cleanups, further merges from Basilisk II tree.
