The only time the card will autonegotiate is when it is started up or
when the switch/hub it is connected to is cycled.

The NIC dirvers (modules loaded at startup) have settings that can be
set in your /etc/modules.conf file.  I.E. the e100 module can be forced
to 100 Full duplex with the following entry in the /etc/modules.conf
file: 

alias eth0 e100
options e100 e100_speed_duplex=4

Other drivers/modules have different options.  Do a strings on the
module or read the manual to find out how to set your NIC.
