 OK, my apologies for not being more thorough before posting -- the
store-bought (not home-made) cable i was using with the card seems to have
been the problem.  I got another CAT 5E cable today, and when i plug it
in, success!:

sarasvati:/tew/001/rdist # ifconfig re0 
re0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        capabilities=87<IP4CSUM,TCP4CSUM,UDP4CSUM,TSO4>
        enabled=0
        address: 00:e0:4c:77:79:80
        media: Ethernet autoselect (1000baseT full-duplex)
        status: active
        inet 192.168.100.99 netmask 0xffffff00 broadcast 192.168.100.255
        inet6 fe80::2e0:4cff:fe77:7980%re0 prefixlen 64 scopeid 0x3


From /var/run/dmesg:

re0 at pci0 dev 14 function 0: RealTek 8169S Single-chip Gigabit Ethernet
re0: interrupting at dec 6600 irq 35
re0: Ethernet address 00:e0:4c:77:79:80
re0: using 512 tx descriptors
rgephy0 at re0 phy 7: RTL8169S/8110S 1000BASE-T media interface, rev. 0
rgephy0: 10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseT, 1000baseT-FDX, auto


I think the problem i was having with the other machine (and a home-made
cable) was related to using ukphy instead of rgephy.

Thanks for your help, as well as the others!
