Well, from 1.4 to 1.4.2, you don't even need COMPAT_14 -- there isn't a
difference in the syscall ABI.  Just a kernel update should be perfectly
fine.

Do note, however, that the ipf and ipnat tools will be incompatible, because
(IIRC) a new version of ipf was pulled up between 1.4 and 1.4.2.  If you
don't use ipf or ipnat on that box, you're safe; otherwise, you need to
extract the 1.4.2 base.tgz too.
