maybe restricting any TIOCLINUX sub features that implement anything related to selection would be a good option. The gpm daemon runs as root anyway.

Do you see any risk left if
TIOCL_SETSEL
TIOCL_PASTESEL
TIOCL_SELLOADLUT
are no longer accessible to non-privileged processes?

I think that should be fine.
