here's a program passed on to me from a kind soul as sequent..
----cut here--------cut here--------cut here--------cut here----
#!/bin/csh -f
#	runs X server and ensures keyboard doesn't hang
set oldkey = `kreset`
set server = X
cd ~
$server >& ,server
kreset $oldkey
---and here---and here---and here---and here---and here---and here
#include <stdio.h>
#include <sys/types.h>
#include <sys/file.h>
#include <sys/ioctl.h>
#include <sundev/kbio.h>
#include <sundev/kbd.h>

main (argc, argv)
int     argc;
char   *argv[];
{
    int     oldtrans;
    int     newtrans;
    int     kfd;

    kfd = open ("/dev/kbd", O_RDWR);
    if (kfd < 0) {
	perror ("open");
	exit (-1);
    }

    if (ioctl (kfd, KIOCGTRANS, &oldtrans) < 0) {
	perror ("KIOCGTRANS");
	exit (-1);
    }
    printf ("%d\n", oldtrans);

    if (argc > 1) {
	newtrans = atoi (argv[1]);
	if (ioctl (kfd, KIOCTRANS, &newtrans) < 0) {
	    perror ("KIOCTRANS");
	    exit (-1);
	}
    }

    return (0);
}
