using the zoom slider on Microsoft keyboard

[Richard KLINDA <rklinda@gmail.com>]

The Microsoft Natural Ergonomic Keyboard 4000 has a zoom slide at the
center of the keyboard.  Here is a picture:

doesn't report this button upon pressing it, so it is unusuable under X.

But there is a trivial patch floating around, that makes this button
(actually, it is two buttons, up and down) usable:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/264287 (a search
for the word KEY_ZOOMIN will get you to the actual patch on the page).

Would it be possible, to incorporate this patch into Debian's official
kernel?

Thanks in advance,
Richard
