I'd honestly be surprised if the readahead scripts are the culprit - how
did you identify readahead as the problem?  The "brokenness" is really
mostly about inefficiency, as far as I know.

...but anyway, just boot into single-user mode (append "single" to the
boot commandline) or use interactive mode as others have suggested, to
chkconfig it off.
