Obviously. What sort of remote display are you trying to use?

That's TIOCSTI, "simulate terminal input" on standard in. It looks
like a fairly disgusting hack to me (ie. simulate terminal input rather

Could you apply this to /sys/i386/linux/linux_ioctl.c and see if it
appears to work? If so, I'll commit it.
