What is a "legitimate patch?"
KPIs like kauth let a 3rd party product interpose itself into kernel
processing at well defined spots without having to patch it. The
only reason to "patch" the kernel is to fix a bug in a particular
kernel version if Apple isn't willing to roll a fix into the next
update (which happened in Tiger once most of the engineers were
concentrating on Leopard).
But it's a fallback. Start by describing what you're trying to do
and ask for a KPI to do it (via bugreporter.apple.com so that it gets
tracked). Saying "I want a generic way to patch the kernel" doesn't
make a lot of sense.
