OK, the file listing of /boot from your last mail and now grub.conf, they
look quite good. grub.conf has been updated by the kernel update, and also
a new initrd-2.6.9-100.EL.img has been created, so that doesn't look bad.
The only thing I'm not really sure is if grub is installed correctly now.
Maybe you have to run grub-install again to be sure but I'm just not so
sure about grubs internals. Maybe someone can tell you more about this.
As someone else mentioned, it's a very good idea to have a current CentOS
4.8 disk at hand so you could boot into rescue mode with 'linux rescue' at
the boot prompt if somethings goes wrong.
