There was work done in the linuxolator to make this possible. There  
was also some work done in the TTY code, to seperate COMPAT_43TTY and  
COMPAT_43. I don't know if this is already done in 5.4 or 6.1. If  
there exists COMPAT_43TTY and you don't need the linuxolator, you can  
give it a try.

Removing COMPAT_43TTY will break some ports according to phk.

Bye,
Alexander.
