I think "out of range" is better than "invalid number".
-5 is a valid number.
Just a minor nit, feel free to ignore this one. :-)

Strtol() reads freshly malloc-ed memory before anything has been put there.
Perhaps:
case 'c':
{
long node_num;
node_num = strtol(optarg, NULL, 0);
if ( (node_num < 0) || (node_num > MAX_BOARDS) )
err(EX_USAGE, "%s:node out of range", __func__);
crom_string = malloc(strlen(optarg)+1);
if (crom_string == NULL)
err(EX_SOFTWARE, "%s:crom_string malloc", __func__);
strcpy(crom_string, optarg);
...
}
case 'd':
================================================================================
case 'u':
current_board = strtol(optarg, NULL, 0);
Does this need a range check?
