So this is the part that's going to stay #370651.  The rest of this mail
is about -1.

Okay, got it.  I'm willing to write a patch that also explains the
option without compiling a kernel.  But first I need to learn how it
really works.  I'd like the kernel people to stay tuned and help me
figure out what to do.  Manoj's input is probably also needed for the
proper kernel-package options and targets.

Indeed, better, but not sufficiently.  It runs make oldconfig and starts
compiling, but then fails:

make[4]: Entering directory `/home/frank/src/linux-source-2.6.16'

  WARNING: Symbol version dump /home/frank/src/linux-source-2.6.16/Module.symvers
           is missing; modules will have no dependencies and modversions.

Hit return to Continue

So the first thing that's missing is the file Module.symvers, later on
also scripts/genksyms/genksyms is missing.  Both seem to deal with
modversions.  Any idea which target I need to call to get that?

TIA, Frank
