I missed the beginning of this thread, but as I understand it:

1. the caps lock key does not generate a key-up event
2. you want to have a control key there

No problem, unless you intend to play Quake. You can fix the key
in software. When you get any key-up event, do this:

if(crummy_key_down) queue_crummy_key_up_event();

So for a Ctrl-A you get:

1. crummy key down
2. 'A' key down
3. 'A' key up
4. generate synthetic key-up event for the crummy key

This is a wee bit annoying if somebody taps the crummy key
while you are away from your keyboard, so one might also add
a 5-second timeout. You could also/alternately let a second
key-down for the crummy key cancel out of crummy-key-down mode.

You might not even need to hack the kernel. Linux already has
dead-key support which might do the job. Use the console tools
to adjust things as desired.
