Supported Network Cards? Please

Hello--
I am trying to set up a Dell PowerEdge 600SC 1.8 GHz, 512 RAM server to run
ColdFusion MX.  I understand fully that I have to be RH 7.2 and under for
the Verity searches to work (I've had RH 7.3 and 8.0 running all to no avail
with ColdFusion/Verity).

HOWEVER, I can't get either of my two network cards to initialize in 7.2.

**The server has a Broadcom NetXtreme Gigabit Copper card in slot 3 that I
can configure in the GUI install in 7.3 and 8.0, but not in 7.2.  I see that
it uses the tg3 driver in 7.3 and 8.

**The server also has an Intel Pro 1000 MT Gigabit card on the motherboard.
This card (in my RH 8 installs) likes to use the e1000 driver.

I've tried to use the Network Config GUI tool in 7.2 (after i install, not
during the install), but all I get is "Network interface failed to
initialize.  Check your settings and try again."  I've also tried
editing/creating the following text files:

**/etc/resolv.conf
nameserver 64.238.96.12
nameserver 66.180.96.12
search localdomain

**/etc/sysconfig/network
NETWORKING=yes
HOSTNAME=localhost.localdomain
GATEWAY=10.0.1.1

**/etc/sysconfig/hwconf (which always detects my network cards, but lists
the driver as "unknown".  i put in the correct driver names [tg3 and e1000]
and save the file)

**/etc/modules.conf (i add the following lines)
alias eth0 tg3
alias eth1 e1000

**and i create /etc/sysconfig/networking/devices/ifcfg-eth0:
DEVICE=eth0
BOOTPROTO=static
BROADCAST=10.0.1.255
IPADDR=10.0.1.130
NETMASK=255.255.255.0
NETWORK=10.0.1.0
ONBOOT=yes
USERCTL=no
PEERDNS=no
GATEWAY=10.0.1.1
TYPE=Ethernet

**i also create an ifcfg-eth1 that has a different IPADDR

In my Service Configuration GUI tool, I note that Network is checked;
however, I don't see even a FAIL message on my boot up text screen where it
goes through all the services and configurations.

In my .../net/modules directory, i see e1000.o, but no tg3.o (i think).  do
i need to compile those or install those or something?

Any help (recommended books, recommended Network cards i could buy for 7.2
that you guys are using, web pages etc.) is greatly, greatly appreciated.

I sincerely don't want to have to put Windows on this server, but if i can't
get this 7.2 on the network, using it as a web server probably won't get me
very far :-(

Thanks in Advance--
Jason
