I'm used to looking for something stupid that I do so I can't help but notice something missing. In the list of commands for the new kernel, I notice the command to copy the old config over is missing. You did copy the config over right? When I run into this, it's because I forgot to put the root file system type in the kernel. Example: The root partition has ext3 and I forgot to build it into the kernel. Some people out of habit build it has a module which also doesn't work. ^_^ Also, make sure the stage files are in /boot too. Hope that helps.
