Kernel Downgrade?

Folks, Here's another fun one. I made the mistake of letting YOU run "hands free". Among other things, it installed the 2.4.199 kernel. This broke several things on my system. Is there any reasonable way to "downgrade" to 2.4.166? I tried just booting the alternate kernel, and got a panic of not being able to mount the root OS. I'm guessing the answer is No, but thought I'd check. -- -Josh Berkus Aglio Database Solutions San Francisco
