I had a quick look at the sources for that the other day, and I actually 
think it now uses the kernel's input event system, and the device nodes in 
/dev/input. Didn't look any deeper as to how it determines what is a keyboard 
etc, but this is what BrlTTY uses for keyboard listening, same with Fenrir, 
even the GUI stack uses these device nodes these days.

So if I am correct, a patched kernel should no longer be required.
