GPS manual configuration (M8N doesn't work with Arduplane)

I’ve just discovered that with latest beta my Arduplane doesn’t recognise M8N GPS module.
This module is shared with other equipment like beacon and video telemetry, and so it can’t be auto-configured by Ardupilot as it won’t work with that equipment.

Setting GPS Serial port to protocol 5 and 115200 rate doesn’t help. Arduplane reports - No GPS.
GPS is set to 115200 and works well with any other devices.

Is there the way to configure GPS manually in U-Center to be compatible with Ardupilot too?
