Before bisecting, I tested my older kernels back to 3.8.9 (where backlight didn't work). 3.8.9 didn't show any ^@ when using the Brighter/Darker key combination. 3.9.4 (which was my first kernel with working backlights) already shows the ^@, so I guess it's not a kernel but a glibc regression. Sorry for the noise. Have a great weekend!
