Tried to boot with the following kernel parameter (as suggested here: http://brettshaffer.com/blog/linux/fix-ubuntu-screen-brightness-problem /comment-page-1/):
nomodeset acpi_backlight=vendor Which makes the brightness keys work on my ideapad u350. But in return the graphics aren't that nice during boot, low resolution of the ubuntu boot screen (something around 640x480 I think). Hope somebody can get it work without the nomodeset.
