A fresh install of openSuSE 11.4 on my Samsung N130 netbook prevents kernel
module samsung_laptop.ko from being loaded. This worked with 11.3. The dmesg
from an unsuccessfull try "modprobe samsung_laptop debug=1" reads:

After reverting the kernel patch
"staging-samsung-laptop-add-support-for-lots-of-laptops.patch" and rebuilding
the module, it can be loaded and works like in 11.3. The dmesg output now
reads:
