I got a working kernel by

 0) pick the arch, board, target filesystem options, etc.

 1) do a "make" and build everything (including a non-working kernel)

 2) overwrite output/build/linux-2.6.30.2/.config with my old
    but "working" config file.

 3) "make ARCH=arm oldconfig" in the  output/build/linux-2.6.30.2
    directory

That doesn't feel like the proper way to do it, but it seems to
have worked.
