You might use an "options" line in /etc/modprobe.conf. The options are
documented in kernel-doc. For example,
$ more /etc/modprobe.conf
alias eth0 e1000
alias eth1 e1000
options e1000 Duplex=2 Speed=100
Alternatively you can add the line.
"/usr/sbin/ethtool -s eth0 autoneg off speed 10 duplex half"
to
"/etc/rc.d/rc.local"
Minus the quotes and assuming that ethtool is located in /usr/sbin. I
do essentially the same thing to set Wake On Lan to on at boot.
