Backup kernel - confirmation

[Norberto Meijome]

quick question - I have a remote box with SMP/HTT disabled, but I'd like 
to see how it works with it. If I make a copy of my current kernel to 
/kernel_orig, I should be able to install the SMP one as /kernel, and if 
hell breaks lose, I should be able to point it to /kernel_orig ... right?

any caveats for this? ( I do off-band access to the server)

thanks in advance,
Beto
