Just test what I described: do a "make oldconfig" (do it twice, if
the first one needs to actually get some input). Do it on 2.6.35, and
then on the current tree. Look at the _huge_ difference in output.

I just did a quick git bisect. It's introduced by commit 4062f1a4c030
("kconfig: use long options in conf") by Sam Ravnborg. Apparently that
thing is totally buggy, and doesn't just change the option names, but
actively breaks them.
