well..if all works oke, i don't think there's a need to do that.
but you could try and learn how it works anyway, so when running into some prob's
in the future ( requiring a kernel-compile ) you know what to do.
so ....if you have some spare time, just try it.
( just get the latest sources at www.kernel.org
and read the sticky howto on this forum )
and it's fun too
