It's strange that no other FN keys work.
When you add "NC10" to the list of supported devices from hal, almost all of the FN keys should be automatically enabled.
To be more precise, these are the keys which should work with no additional work:
FN-ESC, FN-F2, FN-F6, FN-F10, FN-F11, FN-F12, FN-LEFT, FN-RIGHT, FN-UP, FN-DOWN.
The FN-F3, FN-F5, FN-F7, FN-F8, FN-F9 keys should be enabled too, but not mapped to anything. You can map them manually to launch a program or a script. You can find an example of how to do this in my "how to enable wireless" thread
, where you can find instructions to map the FN-F9 key to a script that toggle wireless on/off.
For replicating the same functionalities given by FN-F5 and FN-F8 with Windows, I'll write an howto as soon as possible.
The FN-F4 key is the only one I have not tested. After a little edit of the usual hal file, it makes the screen "flicker" when pressed but I can't say it's really working.
