Well, it of course has to be right after I fix one problem, another comes rolling along. I updated gdm, and tweaked the configuration file a bit.. Then, after all was updated and configured, I went to go log in to a GDM session, though nothing comes up.. I'll either get a blank screen, or the Debian splash.. And that's it.. My GDM log only shows one problem, but I'm not sure if this would be it... Here's the log:

Module Loader present

Any suggestions would be appreciated.. Take it easy.

If you didn't tamper with XF86Config-4 and have just tweaked gdm then you can restore the gdm by doing apt-get --purge remove gdm then apt-get install gdm.

Ok, well, I just found something else out.. Whenever I remove dhcp
from my loopback interface in the interfaces, GDM will start fine.
Though, when dhcp is removed from the loopback interface, I am not
able to get connected to DSL.. Is there any way around this?

Please post your /etc/network/interfaces because it isn't clear what you doing. If you want to automatically get a lease you should have an entry like;

auto eth0
iface eth0 inet dhcp

Problems with getting a lease or finding an ip address can cause the system to stall while it tries and it can be lengthy till it abandons the attempt.

Ok, well, I do have my eth0 interface configured correctly,
and here is my interfaces:

auto lo
iface lo inet loopback dhcp

auto eth0
iface eth0 inet dhcp

And that's it. I know that there are too many options on the lo
interface, though right now, that is how I am getting connected.
But, with the dhcp option, GDM hangs after login, and without it,
I am unable to connect... Take it easy

try this first

dpkg --purge gdm

and then do

apt-get install gdm

I don't think that the loopback interface is valid and I cannot see or find any reason to structure it like that. The loop back connects to your local 127.0.0.1 server. This should have no effect on the network cards or their connection to another network. I am not networking expert and perhaps this question should be addressed in the network forum where other more experienced than me can address this.

I would just remove dhcp from local which means:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
