Ah, I guess we only steal the com(4) ones when we find it through
pluartcnattach:
/* Look for major of com(4) to replace. */
for (maj = 0; maj < nchrdev; maj++)
if (cdevsw[maj].d_open == comopen)
break;
if (maj == nchrdev)
return ENXIO;
cn_tab = &pluartcons;
cn_tab->cn_dev = makedev(maj, 0);
cdevsw[maj] = pluartdev; /* KLUDGE */
