How to distinguish which hifiberry device is mounted ?

Is there any method to distinguish what hifiberry hardware is mounted on the raspi ? *Before* loading any drivers/modules.

The idea is to load the right modules on boot and patch the mpd/alsa configs depending on the hardware.

I have 'several' hifiberrys up an running and would like to 'automagically' modify the config files on installation.

maybe some i2c tools ?
