How to increase brightness in smaller steps?

I have a Lenovo Thinkpad T60 running Oneiric. According to the files in /sys/class/backlight, I should be able to adjust the brightness level to a number between 0 and 7 (and I am able to do this successfully in terminal using

echo 4 > /sys/class/backlight/acpi_video0/brightness

). However, when using the keyboard button (Fn+Home, Fn+End), the brightness levels adjust by increments of three. For example, if the brightness is all the way up at 7 and I press the button once, it lowers to 4, then again to 1, then 0. I would like to change this so that it changes in increments of 1. E.g. It starts at 7, lowers to 6, then 5, and so on. Ideas?

I'm not sure about those numbers, but on my HP laptop I used xbacklight to change my brightness. The brightness varies between 0 and 100 and pressing the brightness up/down keys changes the brightness by 10. I wanted something like five, so I mapped a key to the command

xbacklight -inc 5

and

xbacklight -dec 5

You might be able to use this as a workaround to your problem.
