So how does this currently happen, the unmounting? Does the mmc1 card
just disappear from /dev/ without any safe unmount? I don't understand
how the current setup can work from a userspace point of view.

Userspace could react on kernel events that tell it the cover is open,
but I assume the kernel doesn't just decide to nuke the node from /dev/,
so in that case the current DTS setup still doesn't make sense, right?

What am I missing? Could you describe how this would work in a 'real
life' scenario?

Cheers,
Merlijn
