I think I have something better still. I have a script (evolved from
the PCMCIA Configure script) which just looks at your current kernel
and available modules, and generates .config, version.h, config.h, and
modversions.h.
(the reason this is nice, is that it lets you build modules given only
a clean set of header files for the current kernel: you don't need to
unpack a complete kernel source tree, and don't need to rebuild your
kernel just to get a consistent .config/autoconf.h/etc that matches
the kernel you're running. Which is much closer to a turnkey solution
for the average linux user running a stock kernel that came with their
distribution)
I'll attach it here... it's a bit long but not too horrible. It does
not reconstruct a complete .config file, but does determine all
options that impact the layout of kernel data structures, at least for
x86. It also determines a bunch of things that are probably less
useful for module building. It basically reports most things that are
easy to figure out from info in /proc or /lib/modules.
