With Julian's coaching I've modified my if_hme_pci.c to look like:

--------------------------------------------------------------------------
...
#define PCI_EBUS2_BOOTROM       0x10

                &romt, &romh, 0, &romsize) == 0) {

                /* read PCI Expansion PROM Header */
                bus_space_read_region_1(romt, romh, 0, buf, sizeof buf);

                        (buf[PROMHDR_PTR_DATA + 1] << 8))) >= 0x1c) {
printf("in the read PCI Expansion PROM Header\n");
                        /* read PCI Expansion PROM Data */
                        bus_space_read_region_1(romt, romh, dataoff,
                            buf, sizeof buf);

hmehexprint("promdat ", &promdat, sizeof promdat);
hmehexprint("bufprom2", buf+PROMDATA_DATA2, sizeof promdat2);
hmehexprint("promdat2", &promdat2, sizeof promdat2);

                                sizeof promdat2) == 0 &&
                            (vpdoff = (buf[PROMDATA_PTR_VPD] |
                                (buf[PROMDATA_PTR_VPD + 1] << 8))) >= 0x1c)

The last 3 octets for the HME's on this card are:

00:29:32
00:29:33
00:29:34
00:29:35


If I don't comment out these lines, we don't get make it in to pull MAC:

//                          memcmp(buf + PROMDATA_DATA2, promdat2,
//                              sizeof promdat2) == 0 &&

If I do comment them out, my dmesg becomes:

While one MAC addr is better than no mac addr, I'll bet that something else
is missing -- unless this is all the code looks for is just one MAC addr.
With ttcp I've found the card is able to transmit (picked hme2) just fine:
  67108864 bytes in 55.01 real seconds = 1191.41 KB/sec
Conversely, it CAN'T receive off the network much faster than a modem:
  16777216 bytes in 882.63 real seconds = 18.56 KB/sec
I can make my sandbox system available or I can try different things if
there are suggestions.
