The console passed to TIOCCONS has to be writable, otherwise future console writes will fail. This presumably used to work, but in current kernels (see drivers/tty/tty_io.c:redirected_tty_write) console writes are sent to vfs_write(device), which checks if the device is writable. A quick look in the linux git history doesn't show any recent changes to either tty_io or vfs_write.
