Public bug reported:

Brightness changes in very rough steps on some Machines, but only when
there is the gpm-OSD appearing showing the brightness setting. So the
bug appears not when the session showed is locked, but in an active
session or on the login screen the bug appears.

On my machine (thinkpad X60) brightness changes with two steps between
min and max - these steps are different depending on wether you go up or
down hough. So you can hit 6 settings. I think the firmware is capable I
think 8, surely indepent on wether set higher or lower.

This is found on an X60 Tablet, an Lenovo Netbook (sorry, not sure which
device exactly) and an X201 Tablet. This leads me to believe this is an
issue with the thinkpad-acpi kernel module, which has an proprietary
interface for the screen brightness.
