Do you have the /etc/services and /etc/protocols files? They're part of the 
netkit-base package.

Right, the driver seems loaded. The problem is elsewhere:
SIOCSIFBRDADDR: the broadcast address you are assigning in invalid
SIOCSIFNETMASK: the netmask address you are assigning is invalid

I'm assuming your scripts are ok at this point. First check this (from 

# Obtain all the network card configuration files
        for interface in $(ls /etc/sysconfig/network-scripts/ifcfg* | \
            grep -v ifcfg-lo)

Does a ifcfg* file exist in /etc/sysconfig/network-scripts ?
