I don't know about that.  I found a whole lot of stuff different when
I ran menuconfig and checked the old and new settings.

I just made a partial list by comparing the oldkernel settings in
menuconfig and the new kernel after running make oldconfig.  And this
is only SOME of them, got tired of it part way thru:

Some of these really seem like they should have ended up marked the
same after oldconfig

-------        ---------       ---=---       ---------      -------- 
Automatically append version string on in old off in new
BSD accounting off in old On in new
Export Task process thru netlink off in old, on in new
Auditing support off in old, on in new
Namespc support all off in old all on in new.
Network support/wireless off in old, on in new
Amatuer radio support off in old, on in new
RFswitch subsys support off in old On in new
Networking/ multicasting off in old on in new
Advanced router off in old On in new
BOOTTP off in old on in new
RARP off in old on in new
TCP advanced congestion control off in old, on in new.
ipv6 off in old, on in new

  I gave up after that... so if you think oldconfig means you get the
  same settings by and large... it doesn't.
