Well, I don't see how.

I have a PCI card that only uses 24-bit addresses!  Here's the code:

   (sc->recv_ring + i)->md->md0 = kvtop(lnc_mem);
   (sc->recv_ring + i)->md->md1 = ((kvtop(lnc_mem) >> 16) & 0xff) | OWN;

No, because it didn't look relevant.  The log entry says

 revision 1.95
 date: 1999/04/07 03:59:13;  author: msmith;  state: Exp;  lines: +1 -27
 Remove inactive pmap_setdevram()/pmap_setvidram consumer code.

and it involves removing some #if 0 code and a call to pmap_setvidram().

Is that the change you meant?
