This isn't a kernel problem: it is an X-windows problem.
First question: is X-windows running? If you do ps -A | grep X, do you see anything listed?
Try typing dmesg to see if anything unusual was printed at startup-time that went flittering-by too fast to see.
Look for log-files in /var/log that should contain other boot-time messages.
Do an interactive startup, where the system will prompt you one line at a time for each entry in /etc/rc.d/rc5.d. Look for more messages that you may have not seen.
Are you starting in "runlevel 5" as usual? This is the standard graphical startup mode but there are others (see man init), including one that specifically does not start X-windows.
When dealing with problems like these, it's very important to stop and try to understand them, before you do anything further. If you "try to undo what you did," in the manner of a person fleeing a burning building, you'll only make things worse. The solution to the problem now might be simple, even trivial. The consequences of any ham-fisted effort to get out of it, may be serious.
