Dell laptops have hotkeys on the top of the keyboard for "hibernate",
"cd eject", "battery status" and so on. These can be mapped to
appropriate keycodes, and life is good except for the fact that they
never produce a key release event. The kernel appears to have code to
deal with this for the hangul key, but it's hardcoded rather than
generic.
Is there any way for userspace to tell the event layer that a certain
keycode should have soft-release? If not, would a patch for this be
accepted?

Yes, with a proper DMI entry to activate it would be very welcome.

I was thinking more along the lines of extending the setkeycodes support
to allow a flag to specify it from userspace, though I guess adding some
kernel defaults wouldn't hurt.
