RHEL 4, so you're running kernel 2.6.9 or something? Pretty old...hm.

So, after the power failure "something" happened to your root filesystem. 
I'd suggest to boot off a rescue CD, backup your root partition (dd) and 
then try to e2fsck. The filesystem should then be in a consistent state, 
not sure if it will be usable though. Oh, and try to log all the e2fsck 
output in case you want to analyze it later on.
