Logitech Media Keyboard Elite not fully supported

The media keys on the Logitech Media Keyboard Elite are not supported properly - the layout appears to be different than the others already included and the kernel does not recognise many of the media/extra keys. Currently I have the keyboard hooked up through the USB port.

I have made the following changes to my system to attempt to support this keyboard. Caution: Pressing the key I have mapped as XF86LaunchC (F11 with the F-mode light off) will reliably crash and reboot the system - I have no idea why.

At boot time, the following script is run to map the scancodes to the console level codes. I assume that this keyboard really requires fixes in the kernel code to recognise this keyboard without the use of extra scan codes.

I also made the following alterations to the symbols in /etc/X11/xkb/symbols/inet:

Then the three rules files in /etc/X11/xkb/rules were updated as follows:

After all these changes are made, the appropriate keyboard layout can be selected in the GNOME keyboard layout chooser and used. It appears to function well (with the exception of the system crash for XF86LaunchC).
