Yes, I've seen the thread, and have even commented on it a while back.
But I'm not much for web site comments for debugging. I prefer LKML
email. ;-)

I've read it and I'm still not sure what you deem is broken. By running
the script directly, you will not process any Kconfigs. This means that
dependencies are not processed. This was what the original
streamline_config.pl did, until I received bug reports about it
producing non booting kernels.

Also, make localmodconfig will search for a .config to use if one is not
present. You do not need to copy over one.

Could you send me the output of lsmod, and the .config you started with,
and I can tell you why it selected what it did.

BTW, you can use lsmods from various boxes by doing:

 (on another box) $ lsmod > mymod
                  $ scp mymod myhost:/tmp/

 (on your myhost) $ make LSMOD=/tmp/mymod localmodconfig

and it will use the modules in the file mymod over the local lsmod.
