Attached is my first submitted patch, so please be gentle. It's
actually made against the 2.2.18 kernel, but it should work fine against
2.4.2 from what I can tell.

The patch is extremely simple, but I would welcome testing and feedback
(I am not on the kernel mailing list).

It provides an ioctl call that will forcibly blank the screen. It is
essentially the counterpart to TIOCLINUX, subcode=4.
