Subject: ThinkPad T420 : 8 versus 16 brightness level steps

/'m wondering why under a 64 bit RedHat 6.4 Linux with kernel 2.6.32+X
I do have 16 levels in dimming the display brightness with Fn+Pos1/End
whereas under a 32 bit Gentoo Linux with recent 3.1x.y kernels I do
just have 8 steps from min to max.
