After having answered all those questions :), believe it or not, but on my test machine, I did an upgrade to CentOS 4.3 and tried to reboot and.... it worked !!! I've done the same thing on the production server and, not surprisingly, it worked too. I don't know what happened but I guess there were a missing/not updated package that caused the kernel panic. The file is closed for me :). Thanks to all the people who answered my message. Regards, Gilles, a happy CentOS admin :).
