That changed in Jaguar (or maybe it was 10.1.5) there IS an un-install 
feature on the install disk. It's in the pull-down, (along with a 
terminal window for standalone repairs.) However, I can't tell you how 
well it works, or what is required to make it work. It may only work if 
you have done a "clean install" -- which effectively renames / and 
creates a new one... but you need twice as much free space then.

Usually, it is EXTREMELY painful to roll back ANY OS upgrade. Much 
easier to reload the backup you made before the upgrade. If all you 
upgrade is the Kernel, then that too is easy to roll-back in Jaguar, 
but ONLY upgrading the kernel rarely accomplishes anything other than 
providing for new and different hardware configurations. Once you start 
changing system libraries to match the kernel, you get in to the areas 
of pain. And, I realize that in Apple's packaged Jaguar distribution, 
you don't get "just the kernel, you get a whole system.
