First, remove the device drivers which you aren't using (ISA NICs, NICs
you don't use, SCSI if you use SATA, firewire...)
Get this purified kernel working, then start adding your custom options
little by little.
I'm afraid there's no magic way of doing it that I know of :)
By the way I am unsure what your whole bit about smbfs is about.
Want users to be able to call mount_smbfs ?
I would sooner give them sudo privileges for this very specific command,
than bother hacking and patching the kernel in uncertain ways.
I would also remove unnecessary SCSI support as well as mass storage
USB, USB printer, USB NICs...
Just get shot of everything you don't use to be honest ;)
