The only difference to hardware revision 4 is that the device doesn't switch to VGA mode in case someone happens to touch a VGA register, which should make things more robust in configurations with multiple vga devices. Swtiching back to VGA mode happens on reset, either full machine reset or qxl device reset (QXL_IO_RESET ioport command).
