Do you have a Turkish keyboard? Does it also show the US key layout?
If so, it's not very difficult.

Yes, that's in the keymap definition. Look at
/usr/share/syscons/keymaps/us.iso.kbd, which defines the standard
layout. You would want to create a tr.iso.kbd for your layout.
Here's an excerpt.

025 'p' 'P' dle dle 'p' 'P' dle dle C
The scan code (which in decimal, not octal, despite the leading 0)
represents the key. The next column describes the character generated
by the key alone. The column after that describes the character
generated with the key and the shift key. The column after that
describes the character generated with the key and the control key.
The column after that describes the character generated with the key
and the control and shift keys, and so on. The last column specifies
whether the CapsLock key applies to this character or not.
To change this, just change the characters which are generated by the
key. For example, key 21 is 'y' in the USA, but 'z' in Germany. The
German keymap contains:
021 'z' 'Z' sub sub 'z' 'Z' sub sub C
Note that the control characters have changed too: 'sub' is the ASCII
SUB control character, ^Z. If you leave this as dc4, you'll have the
bizarre situation where the key generates 'z' by itself, but ^Y with
the control key.

Send me the keymap when it's ready, and I'll commit it.
