Will try a bit later, but I suspect this is the wrong direction of thought.

All modules that are needed for the user's keyboard are included in the initrd.

I'd suspect something related to USB power saving. This is the most
frequent reason for USB keyboards and mice to misbehave - the host
just turns them off mistakenly. So
/lib/udev/rules.d/42-usb-hid-pm.rules does look relevant.
