The cover magnet hall-effect sensor is located about 1 inch (2-3 cm) above the bottom of the screen right edge. You can hold a magnet over it and read the sensor change:

No cover magnet:
[root@kindle /]# cat /sys/devices/system/yoshime_hall/yoshime_hall0/hall_detect
0


With cover magnet:
[root@kindle /]# cat /sys/devices/system/yoshime_hall/yoshime_hall0/hall_detect
1


I will add more findings to this thread as I discover them, and you can too.
