Common for NetBSD, or XFree86 on other OS's as well?

There's an VT_ACTIVATE ioctl that would seem to do what you're after.
Be careful - it looks like it uses `1' for the first screen, not `0'.
Something along the lines of:
/* select the console (virtual screen 0) */
screen = 1;
error = ioctl(fd, VT_ACTIVATE, &screen);
showhorned into wsconsctl should be a good place to start.
If we do plan on adding this functionality to, say, wsconsctl, then
we probably should also make a WSDISPLAYIO_ACTIVATE ioctl too...
