Maybe it will be wise to introduce an option "--force-up" for "setkeycodes"? That way we will not have to add patch into kernel driver for every misbehaving laptop, we will just could to add a HAL quirk for particular Fn + keys already defined in 30-keymap-misc.fdi
Same patch is needed for Samsung X360
And many many more Samsung laptops, see Bug #399911
eg. "I have found exactly same problem in lanchpad for Samsung R518, R60, NC20, Q35, Q210, X360.
Eg. Bug #360247, Bug #411031, Bug #253874, Bug #385683, etc."
