Hmm.  A quick look at the diffs show that the old driver had:

!               brdp->panels[panelnr++] = panelp;
!               brdp->nrpanels++;
!               if (ioaddr >= (brdp->ioaddr2 + 0x20))
!                       break;

while the new one has

!                 brdp->panels[panelnr++] = panelp;
!                 if ((brdp->brdtype == BRD_ECH) || (brdp->brdtype == BRD_ECHMC)
){
!                         if (ioaddr >= (brdp->ioaddr2 + 0x20)) {
!                                 printf("STALLION: too many ports attached "
!                                         "to board %d, remove last module\n",
!                                         brdp->brdnr);
!                                 break;
!                         }
!                 }

so AFAICT the only effect of this error message is to document a problem that 
was silently ignored in the original driver.  If there is a problem with the 
new driver I suspect it is somewhere else, but alas I can't offer any clues.

You could try replacing sys/i386/isa/stallion.c with the 1.39.2.1 version.  I 
_think_ this will not care about the other related changes.

Greg.
