You cannot load a module that is already loaded unless you remove it
first.  Reloading it may give you a chance to see error messages you
missed and to crank up the debugging level.  Look at the console
screen and tail /var/log/messages when reloading.  reloading the
module will mess up your routes and you will need to ifconfig
the interface back up (or just reboot).

There is a good chance that you have the wrong gateway, broadcast 
address, netmask, or routes.  If the card was not in the machine
when you installed than none of these would be configured properly.

You may also have a speed/duplex auto negotiation problem with your host.
Read the linux tulip website for information on how to ping.

Here are some commands which might give you some information to explore
in diagnosing the problem:

/sbin/route
ifconfig
netstat -i
tail -200 /var/log/messages | less
/sbin/rmmod tulip; /sbin/insmod tulip   # will mess up routes, reboot later
/sbin/rmmod tulip; /sbin/insmod tulip -debug=1  # syntax correct?
tail /var/log/messages
less /etc/sysconfig/network
less /etc/sysconfig/network-scripts
less /etc/conf.modules
cat /proc/pci      # look for interrupt/ioport conflicts below
cat  /proc/interrupts
cat  /proc/ioports 
ping <your router here>
ping <other host on your network>
ping <host outside your network> 
# do the lights on your card and hub blink in response to the ping?
Download and run tulip-debug

Have you accidently disabled too many services in /etc/rc.d/rc.*/
including core network functionality (like network and inet).
