[c-nsp] connection speed at physical layer

This might be a bit stupid question, but I have following topology:
IBM_T60[eth0] <-> [Fa0/2]WS-C2950C-24
eth0 port is an "Intel Corporation 82573L" GE port and Fa0/2 port in
WS-C2950C-24 switch is of course FE port. I have enabled
autonegotiation on eth0 port, but it advertises only 10BASE-T/Full
mode, so switch port, which is configured to "speed auto" and "duplex
auto", is up with following settings:
Fa0/2 -> T60 connected 1 a-full a-10 10/100BaseTX
Am I correct, that actual signalling on physical layer is 10BASE-T? Or
is eth0 port actually sending at 1Gbps(1000BASE-T signalling) rate and
Fa0/2(100BASE-TX signalling) is sending at 100Mbps rate on physical
layer?
thank you in advance,
martin
