Re: [PATCH] Fix Keymapping for upcoming Dell Laptops

[Jerone Young <jerone.young@canonical.com>]

I left them out on purpose in the resubmit. It turned out that the way
these work (currently) under Windows is that the key press does two
things.
	- it turns off the touchpad through the bios
	- it sends the keypress scan code to the OS

Under Windows the driver/daemon catches the keypress but it's only so it
can show a nice on screen display. Doesn't try to cut it off or on via
the OS.

Currently (working to fix with Dell), If these are mapped under Linux
what happens is. The hardware first cutoff the touchpad, but then what
happens is the software will then toggle this setting. So you end up in
one of two states:
		- never being able to turn off the touchpad
		- never being able to turn on the touchpad

Will submit another patch with these once can get this sorted out.

				Thanks,
