The steps I gave instructed you on the steps to load the working configuration for a new kernel, that at least added the existing modules. With each step that is attempted can you please tell us why it did not work or give the error messages so we can attempt to correct your problem?
Now for the step I gave you, they came from a guide that I have used many times to build a stock kernel in slackware, I hope that they can help you. http://alien.slackbook.org/dokuwiki/doku.php?id=linux:kernelbuilding
And here are two guide to build a kernel on Mandriva.
