There was a change between 2.6.x and 2.6.x+1 where the whole .config  
was rearranged and `make oldconfig` no longer worked. It was a while  
ago, so maybe you don't recall it. I think x was circa 22 or so. It  
was discussed on here at the time, IIRC, and caused filesystems such   
as ext2 (at least) to be unselected if you just ran `make oldconfig`.
