As long as you are running a stock kernel, and using the same or an
upgraded CPU, I would change the MB, boot into run level 3, and let
Kudzu figure it out. In the past, I have had good luck with this.
You will probably have to run the X configuration tool before you
can boot into run level 5. (I am lazy - I run setup and pick the
correct setup option.)

Depending on the old and new CPU's, you may want to change the
kernel and libc to make full use of the new CPU. One thing to keep
in mind - if option 1 does not work, you can always proceed to step
2, and then step 3. Step one will not take long to do, and is worth
it as a learning experience to see just how well Linux does handle
hardware changes. My experience has been that, with the exception of
your X configuration, it handles it very well, as long as you are
not downgrading CPU's. I have not tried to let Kudzu handle changing
the X configuration in a while, so that may even work now.
