anyone know how to force network cards talk at gig speeds when all it wants to do is establish a connection at 100mbits

One of mii-tool's limitations is that it doesn't report gig speeds correctly. From the man page:
NOTE This program is obsolete. Valid media are only 100baseT4, 100baseTx-FD,100baseTx-HD, 10baseT-FD and 10baseT-HD ethernet cards. For replacement check eth-tool.
Using ethtool:
[root@el4-node1 ~]# ethtool eth0 Settings for eth0: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Half 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on Current message level: 0x000000ff (255) Link detected: yes
