Because it was replaced with the LinuxInput driver. It's superseded. See:

http://qt.gitorious.org/qt/qt/commit/3f51c30f030a5517273a62bdd48dfe96c98852ee

No. There's no source or binary compatibility guarantee to Qt internals.

The linuxinput driver.

Take the 4.5 plugin and make it work. Maybe it will work out of the box, maybe 
you'll have to do a lot of work to make it work with 4.6.

Alternatively, find out why the new driver doesn't work for you. The new driver 
simply uses the Linux /dev/input/* device nodes, which should have the correct 
mapping. So it looks like the problem isn't in Qt, but in your device driver 
or your keyboard keys.
