I own a Fujitsu Lifebook S7210. Basically, the situation is the same as described by Bruce Wolfe. The Fn+F6/F7 keys were not working at all on Hardy. I wasn't able to change screen brightness in any way. xbacklight could dim the screen, but I think it wasn't using ACPI and I didn't have the feeling that I could use my laptop longer, i.e. it probably didn't use less power.
Now with Intrepid, the keys are bringing up a little meter and change this supposed brightness value, and /proc/acpi/video/GFX0/LCD/brightness reflects those changes too... but the *actual*, observed brightness doesn't change. Unlike Bruce, plugging/unplugging AC doesn't bring up anything. I am ready as well to run some tests and to help in fixing this... P.S.
