ok, wrong assertion from (I really don't sleep enough. Still waiting
for the baby to sleep at night ;-).
The control I've mentioned is in drivers/main.c

323         /* don't let the user shoot themselves in the foot */
324         if (!strcmp(var, "driver")) {
325                 if (strcmp(val, progname) != 0)
326                         fatalx("Error: UPS [%s] is for driver %s,
but I'm %s!\n",
327                                 confupsname, val, progname);
328                 return;
329         }

but it's void in your mentioned case, since progname and
ups.conf->driver will be the same...
