Yes, went through the whole thing and still didn't understand this.  For example,
it says, "For backwards compatibility, the deprecated adb_buttons= kernel argument
still uses ADB keycodes" but this is clearly failing for everyone.

I had thought there were now two mappings: ADB (for compatibility, e.g. in
.Xmodmap) and "Linux", which is why we use "IMPS/2" as the X mouse mapping...

So I went to an i386 box with PS/2 keyboard, did xmodmap -pke, and the resulting
mapping of course had nothing to do with the mouse button emulation codes.  The
PS/2 mouse is the "Linux" standard, but has nothing to do with the keyboard.  Why
not just a new "Linux" mouse standard too?

So now to deal with an ADB (or other non-PS/2) input system, we need to work with
three sets of standards: ADB, PS/2, and "Linux"- the last of which is part PS/2 and
part something completely different?  And such standby tools as showkey are
broken?  And this in a kernel-image in r2?  Sure, that will be perfectly clear to
everyone the first time.

Maybe you should get some netiquette.  Saying stupid things like this just gets
people mad at you, and puts Debian in a bad light.

With breakage this bad mid-release in stable, and documentation this poor, I expect
the confused posts will continue for another month or two.  Learn to deal with it,
or just use the "delete" button.
