While getting old, everybody tend to write something, but in this case
this and LDD3 is just making money, if any (IMHO).

So, lets study not what to think, but how to think :)

i guess, i've helped once in LKML to get this right.

It's 2.6.18, but i doubt current mainline have any kbuild changes.
Don't know, what's wrong with `.tmp_versions', but anyway:
