It turns out that the card-detection mechanism was somewhat broken on my
device (which does have a regular push slot). It would report card-
detect only when the card was not fully inserted, and stop asserting
card-detect when it was pushed fully.

I used a fitting tweezer to move the mechanical parts around and got it
to also detect the card when it is pushed all the way.

So no change is necessary after all, it was just my device that needed
fixing.

Thanks for the helpful answers!
