The T version of the 7i92 drivers have been include with PathPilot updates for a while, certainly 2.10.1 . The 1100 .ini files all include T and non-T driver loading.
Make sure that the jumper on the 7i92 is set to use 10.10.10.10 as IP address, and make sure it is the only device on your ethernet. And if you have more than 1 ethernet board, take one out. (Linux can not predictably keep an interface as eth0 for some reason. If you need/want you controller connected to internet then use WiFi.
