With what I submitted I did not test make oldconfig, only make 
menuconfig due to gcc 4.6.0 giving me a slew of warnings.
 From looking at make oldconfig I do see a more detailed explanation of 
what each option is(last I remember it was more of a line with y/n)but 
then again you could be seeing something completly different.

keep in mind not sure if this is with kconfig merge or not due to me 
seeing make oldconfig react the same way with 2.6.35-rc6-00191-ga2dccdb
and the current(pulled a few minuetes ago)
but look kind of differently with 2.6.34(but could be wrong due to not 
using make oldconfig that much).
Now if this is with what I submitted then I'll have a look at it and see 
if I can get this fixed.
