Nice to hear GParted worked good.
As a side note, Qtparted is on the live CD.

That kernel came out before, or right during the time that Core DUO came 
out.  It doesn't work well with it.  The two options are
1 - Update the kernel to the newest one.
2 - re-install with S.L. 4.4.  A bit drastic, but should work.

The driver for this is NOT built into the kernel, even in S.L. 4.4. 
You'll need to talk to RedHat about that.
But we do have a solution.  If you installed S.L. 4.4, it should have 
been installed during the install.
(Please note that as far as I know, we're the only RHEL based 
distribution that has Intel's 3945 working.  Much thanks go to Jarek for 
getting this working.)

The following yum command will get you the right kernel module, 
firmware, and wireless deamon.

yum --enablerepo=sl-contrib install ipw3945d ipw3945-firmware 
kernel-module-ipw3945-`uname -r`

After that, there is much discussion about how to get it working, 
because you have to have the ipw3945 deamon running before you can use 
it.  Here were my instructions, others can feel free to chime in with 
better ideas.

You need to get your computer to recognize the card.  I have found that

   /etc/init.d/kudzu start

works pretty good.  But then you need to get it so that the driver and 
the deamon start during startup.  I don't see a startup script yet, so 
what I did on the laptop's I worked on was edited  /etc/rc.sysinit

And put in the lines

   modprobe ipw3945
   sleep 1
   /sbin/ipw3945d

right before the line that says
# Now that we have all of our basic modules loaded and the kernel going,

At this point, your machine will see the card and load the module. 
Setting up your network connection is up to you.
For this laptop, the NetworkManager worked, so I used it.
As root:
   /sbin/chkconfig --level 2345 NetworkManager on
   /etc/init.d/NetworkManager start
As a user (whether in Gnome or KDE):
   /usr/bin/NetworkManagerInfo

You will then get a radar on your system tray.  Click on it, and it will 
show you what networks are visable.  You might have to initially click 
on it, then click on it again.  Then select whichever network you want 
to connect to.  If that network needs a password, it will ask you for it.
