1) The Kernel Documentation is always out of date. That is because the Linux kernel is a work in progress and probably will be until 2.6.30 sometime."

This might have been true during the old stable/development split model. With 2.6 development happens in -mm tree which is a soft fork and major features get added to every release which means the rate of change is always high and 2.6 will always be "work in progress" as you call it.

"2) I suspect once the 2.6 API is frozen and work begins on 2.8 or 3.0, documentation will firm up.
Linux kernel internal modules API never freezes. User space API and ABI is always stable. With the 2.6 development model dont expect a 2.8 or 3.0 anytime soon. It might never happen unless somone manages to come up with a change so far that cannot be incrementally pushed in and deserves a complete fork.

This is a bit off topic but probably useful to understand.
