paste_selection still says

/* Insert the contents of the selection buffer into the
 * queue of the tty associated with the current console.
 * Invoked by ioctl().
 *
 * Locking: called without locks. Calls the ldisc wrongly with
 * unsafe methods,
 */

from which I deduce that with everyone using X nobody ever bothered to
fix it. So before you look too hard at the speakup code you might want to
review the interaction with selection.c too.
