If you guys are trying to get your screen resolution to stay at a resolution that OS X won't load to, follow these instructions:

1) Download cscreen and save to desktop.

It is a command line utility to allow screen changes.
2) Once it has been saved and a Disk Image has appeared on your desktop, open terminal and type in:
sudo cp /Volumes/cscreen/cscreen /usr/bin
3) Open Applescript Editor. Keep in mind you can set whatever numbers you want for your resolution (eg. 640 x 480 or 800 x 600). You can also set your refresh rate (eg. 60).
On Applescript type in:
on run

do shell script "cscreen -x 640 -y 480 -r 75"

end run
4) Hit Run button on top of Applescript editor to see if it works. If it does, go ahead and save it as an "Application." This will be under File Format on the Save As window. You can save it anywhere you want, the Documents folder is probably the best place.
5) Then go to System Preferences and pick "Accounts", then pick "Login Items" tab. There you can add the applescript that you have just created.
6) Restart your computer to see if it works.

Goodluck.
