You need to enable support for the LED class in the linux kernel:
CONFIG_LEDS_CLASS=y

Once you have done that, the fujitsu-laptop driver will register a LED
that you can toggle on & off. If this does not work, could you load the
driver with full debugging:

modprobe fujitsu-laptop debug=0xffff

Also, please attach the following file to your e-mail:
/sys/firmware/acpi/tables/DSDT

(You can decompile it using iasl -d)

Obviously I hope it'll Just Work(TM) for you, but if not, I can
probably help :)
