fsc_btns module doesn't know T900

    I have a Fujitsu T900.  When I load the kernel module, it says
    fsc_btns: found: Unknown (using defaults)

    I don't know how much that affects the functioning of the module, if at all, but I'd be happy to help with the efforts to teach the module about the T900 if someone has a bit of time to guide me through it.

    it affects the keymap. So if all key works as expected, you can ignore this message or better post the exact product name from the DMI (dmidecode). If some keys doesn't work, I'll provide you a test-keymap.

    Thanks for the quick reply.  I somehow managed to miss it.
    dmidecode provides a LOT of output.  The two instances of the word "Product" in the output are
            Product Name: T900
            Product Name: FJNB204
    I'm guessing the former is not interesting.  Is the latter?

    If that's not what you are looking for, can you give me more specific instructions, and I'll be happy to send it.

    Only "T900", not more? - Okay. What is the "Manufacturer" in the "System Information" session (exact spelling please).

    Do you have some issues with the selected "unknown" keymap (non-working keys or incorrect assignment)?

    To answer your question about the button mappings… I think they are
    OK, but that might be an issue of me not understanding what is
    supposed to actually be happening (is there documentation somewhere I
    am missing?).  Without fscd running, I get Next, Prior,
    Xf86RotateWindows, Ctrl, and an Alt key with a two second (give or
    take) stickyness.

    With fscd running, I can access the screen brightness up and down
    features and the configuration feature, which cycles me through three

    So it is probably good, but I don't know for sure.
