The idea is to run "make oldconfig" before "menuconfig". Menuconfig
sometimes leaves the .config file in an illegal state and als can get
confused at strange .config files, oldconfig fixes that.

Just checked: the 2.6.8.1 kernel from kernel.org contains the same
error. The 2.6.10 tree I have over here doesn't have that error, so
it's fixed somewhere between 2.6.8 and 2.6.10.

Don't know if it's still relevant, but maybe you should file a bug
against the package. If you're using a kernel.org kernel, you should
use the latest stable version (2.6.12.3 at time of writing).
