No, it is as Kumar said. And you don't have to download the full source
if you have 2.6.29 already. With your proposal, you would need 2.6.29,
_every_ patch-2.6.29.y and apply them consecutively -- this becomes
rather tedious if y is large.

I always download linux-2.6.x.tar.bz2 and patch-2.6.x.y.bz2.

Actually, "make oldconfig" is the best you can do to check every new
kernel option. It takes a bit of time if going from 2.6.x to 2.6.x+1,
but for most questions asked you can just press Enter.
