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 :)
