I think this is either a dupe of bug #819002 or should be fixed in a
similar manner. (I.e., the patch on that bug might not fix this
particular model, but it might simply require adding this model number.)
The fix improves the ACPI support for Vaios in the linux kernel.

This is still not working in Oneiric.
The OSD indicators appear but the back-light doesn't change.
IIRC at some point in time this project
https://github.com/guillaumezin/nvidiabl allowed me to actually modify the
back-light, any chance it can be included in Ubuntu?
Anything else I can provide
This is still broken on 10.10 now even the OSD indicators are gone.

Got same bug, or at least closely related. nvidia GT216 [GeForce GT240M] does
not respond to brightness commands.
This laptop is a new Fujitsu Amilo Pi 3560. The keys are Fn-F8(down); Fn-F9(up).
