No - this is a new 2.6 feature. There has been significant wah
(heated discussion) about this feature being missing from previous
kernels - as it IS a complet PITA trying to rebuild a kernel for a
machine when you've lost the .config file and you just want to add one
module / make some small change / upgrade by one minor version / whatever.
"make oldconfig xconfig" will pull in all the settings from a
.config file in the same directory and preset all the parameters that it
finds. Then it will happily dump you in an X interface to configure the
rest of them (or change the previous settings of course.) It's a good
way to do things between minor releases / where you've already built a
kernel for a machine.
I tend to start afresh for new major releases of kernels to be
honest - so much tends to change between them and certain combinations
of settings are sometimes no longer advisable / available / a good idea ;-)
