Hi Martin -- I went through the steps outlined:

vanhoof@reptar:~$ /lib/udev/findkeyboards
AT keyboard: input/event5

vanhoof@reptar:~$ sudo /lib/udev/keymap input/event5 > orig-map.txt

... however when attempting to generate output with:

vanhoof@reptar:~$ sudo /lib/udev/keymap -i input/event5

... no events are registered at all when using Function+up, or
Function+down. Both Function+left/right (volume), and all the
directional keys work just fine:

vanhoof@reptar:~$ sudo /lib/udev/keymap -i input/event5
[sudo] password for vanhoof:
Press ESC to finish
scan code: 0xC8 key code: up
scan code: 0xD0 key code: down
scan code: 0xCB key code: left
scan code: 0xCD key code: right
scan code: 0xAE key code: volumedown
scan code: 0xB0 key code: volumeup
[...]
scan code: 0x01 key code: esc

I checked on Lenovo's site, and there are presently no BIOS updates
available for this laptop yet.

Just in-case it is needed, I'm attaching steps 4, and 5 here as well:

vanhoof@reptar:~$ head /sys/class/dmi/id/sys_vendor
LENOVO
vanhoof@reptar:~$ head /sys/class/dmi/id/product_name
3389

Could this just be a BIOS issue, or any other ideas?
