Is there some secret KDE-cult reason for it not working, or are there some kind people in here that can explain to me why: setting keyboard brightness is impossible unless I log out and log back in again. It bothers me quite a lot that whenever I boot up I have to log out to KDM and log back in again to make keyboard brightness work.

Welcome to our openSUSE Forum.
To enable the brightness keys.
Add “acpi_osi=” at the and of the kernel boot parameters. A more permanent option is to edit /etc/default/grub as root.
Next append “acpi_osi=” to the end of GRUB_CMDLINE_LINUX_DEFAULT= .
Open konsole or xterm and type " su - " (without the quotes). Copy and paste the line below and press the <enter> key.
grub2-mkconfig -o /boot/grub2/grub.cfg
Close konsole/xterm, shutdown and restart your system.
Good Luck!
Thank you for taking the time to type out a reply to a post sadly lacking descriptions of what have been tried prior to posting. I’m sorry for not describing in advance what I have attempte to overcome the problem myself.
I’ve tried adding the following to grub : acpi_osi=, acpi_osi=Linux, acpi_osi=Windows and acpi_osi=’!Windows 2012’ Not all at once mind you.
Some of them, like acpi_osi=, works by giving me control over the brightness keys upon boot, but I still have problems. One of the problems is that I do not get the dialog for keyboard brightness when I click the power control icon in the system tray. In and of itself this is no biggie, but perhaps relevant. The main problem is that when I suspend the laptop, and I do that a lot during the day, I lose the ability to control keyboard brightness altogether. If, however, I don’t add any variety of the acpi_osi= command to grub, and log out to kdm and back in again, it works flawlessly.
It is this particular behaviour which made me wonder if there is some kde juju a non-coding user could do to fix it.

You are welcome.
A couple of patches were introduced in October - January 2014 regarding the newer laptops so this may help with the standby issue.
In regards to the “Fn+key” not working, the bug has been reported upstream to the kernel devs. So keep checking when kernel 3.20 and higher are released.
I would recommend reporting this problem with https://bugzilla.opensuse.org/index.cgi so that openSUSE kernel devs are aware of it.
In the meantime update your kernel and kernel sources, kernel-syms to kernel 3.19x.
Here is the repository:http://download.opensuse.org/repositories/Kernel:/stable/standard/
Add additional kernel parameters for some speed optimizations and longer battery life. Please append to GRUB_CMDLINE_LINUX_DEFAULT= below:
add_efi_memmap i915.i915_enable_rc6=1 pcie_aspm=force drm.vblankoffdelay=1 i915.semaphores=1
For setting brightness considering installing “xev” “xbacklight” and xbindkeys.
**
xev**
Utility to print contents of X events
It creates a window and then asks the X server to send it X11 events whenever anything happens to the window (such as it being moved, resized, typed in, clicked in, etc.).
You can also attach it to an existing window.
xbacklight
Utility to adjust the screen backlight brightness where supported.
xbindkeys
Events Grabbing Program for X-Window
xbindkeys is a program that associates keys or mouse buttons to shell commands under X.
After a little configuration, it can start many commands with the keyboard (e.g. control+alt+x starts an xterm) or with the mouse buttons.
