+/****************************************************************************
+**
+** Keyboard Handling Redesign
+** Copyright 2003, Chris Larson <kergoth@handhelds.org>
+**
+** TODO: (key: . = in progress, x = completed)
+**
+** [.] Tty driver should load its initial keymap from the kernel,
+** thereby ensuring keymap consistency between X, console, and qt/e
+** [x] Read kernel keymappings.
+** [x] Read kernel keycode -> unicode map.
+** [x] Use them, along with the existing keyM, to push events up.
+** [ ] Create a new table, from transformed keycode -> qt keycode, rather
+** than the existing raw keycode -> qt keycode.
+** [ ] Adapt handleKey to deal with keys that have no unicode value, such as
+** keypresses that are mapped to strings in the string table. (e.g. F keys)
+** [ ] Cursor orientation change based on display rotation should not
+** be bound to Ipaq or 5xxx, but instead as a runtime choice based
+** on whether or not we're using a Transformed display driver.
+** [ ] Double check that VT handling, particularly with regard to switching,
+** is handled properly.
+** [ ] Add a generic means of dealing with additional (outside the realm of
+** ctrl, alt, shift, altgr) modifiers. Also ensure a means of binding
+** a keypress/combination to a 'lock' of said additional modifiers.
+**
