I have to point out an exception to this rule, though. If you are talking
about binaries that link to the kernel, e.g., device drivers, you need to
exactly match the kernel you have installed, or the symbol table entries
won't match up and you will get unresolved symbol errors.

We get tech support calls all the time at work from people who decided to
use the i386 binary on their PIV or Athlon, because "I thought i386
worked with everything".
