In man pages, dmesg and ifconfig of FreeBSD5, GbE operation over
twisted pair is mostly referred as '1000baseTX'.  I guess most of them
should be replaced by '1000baseT'.  1000base"TX" and 1000base"T" are
different standard and they are not compatible ("TX" needs CAT6 cable
and uses pairs in different way).  Also 1000baseTX support is very
rare yet.  I'm sorry I'm not sure if some devices really support "TX".

For example, I have a NIC based on Realtek RTL8169S and its manual
says "It supports 1000BASE-T/100BASE-TX/10BASE-T".

In dmesg:
rgephy0: <RTL8169S/8110S media interface> on miibus1
rgephy0:  10baseT, 10baseT-FDX, 100baseTX, 100baseTX-FDX, 1000baseTX, 1000baseTX-FDX, auto
