Lenovo Trackpoint Keyboard II meida keys (Fn + F9-F12) not recognized

Hi, I recently purchased a Lenovo Trackpoint Keyboard II (Official product page), and it is working fine except for the 4 rightmost media keys. I tested their key presses with evtest:

$ sudo evtest

So /dev/input/event3 is the device for the regular keys and evtest on it did print MSC_SCAN with the scan codes. However for the media keys, only /dev/input/event5 shows events on key press/release, but the events are EV_ABS and ABS_MISC (value 0 on press, 1 on release), which sounds like an absolute position input instead of a keyboard, and all the 4 keys print the same events.

I had experience writing hwdb rules to remap both regular and media keys on a real ThinkPad keyboard, plus I successfully remapped the menu/prtsc keys on this keyboard, but just couldn't figure out how to proceed when evtest doesn't give me the scan codes (and probably not recognizing the device as a keyboard at all)

So I was wondering if anyone has more info on what could be the cause for this, and how may I fix it. Thanks in advance!
