Hi Harvey,

Okay, this seems to be consistent with the manual I linked to in my
previous message.

These hotkeys should already work fine under Linux, i.e. pressing them
should generate input events which you can assign to any action you
please.  If they do not work for you, please let me know so that we can
debug further.

If I did not miss anything in your reports, there are two issues that
require some work:

  - Fixing radio LED detection.  I have an idea how to do this, but
    please mind that I am quite busy lately and cannot guarantee any
    specific time frame for submitting a patch.

  - Investigating the E LED.  This requires taking a look at the DSDT
    dump from your laptop and searching for clues as to how this LED is
    handled.  I will be happy to do that, but again, no promises about
    how much time it will take.  (And given the nature of this task, I
    cannot promise I will find anything reasonable at all.  I also might
    ask you to do some further experiments as I do not have an E751
    myself.)
