Graphics Drivers corrupted

I need to know how to reinstall the correct graphics drivers with my macbook pro... somehow they were corrupted while I was trying to use wine with xquarts.. I would normally know how to do this, however, the screen is totally unreadable when starting up... When using the disk I can boot from it and things look normal, just wondering how to actually reinstall the drivers. I could ssh into it from my ubuntu. but I don't have ssh allowed currently.

Any help other then reinstalling the whole OS would be appreciated. Thanks.
