+**
+** 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.
