Similar problem on my ThinkPad T400, but with steps of two or three.
cat /sys/devices/virtual/backlight/acpi_video0/actual_brightness goes 0 -> 2 -> 5 -> 8 -> 11 -> 14 -> 15 (max), down: -> 13 -> 11 -> 8 -> 6 -> 3 -> 0. Manual setting of each single step via panel is possible.
I haven't had this on maverick, if that is any help.

lshal -m does not generate any output.
