>From the acpidump attached,
we can see that the Fujitsu-Siemens Amilo Pi 2515 backlight control go via ACPI
video extensions rather than Fujitsu platform specific control methods.
So fujitsu-laptop should have no effects on this laptop.
Patch at http://bugzilla.kernel.org/show_bug.cgi?id=10042#c8 is to fix a BIOS
bug which is shown in the acpidump.

BTW: I think there are some problems on probing a device in fujitsu-laptop
driver. Generally speaking, the .init call should do nothing except registering
the driver. And the driver .add methods should be used to probe a compatible
device, if there is any, and build the sys backlight I/F for this device. Or
else users may be confused by the /sys/class/backlight/fujitsu-laptop/ like in
this bug report. what do you think? :)
