By the way, and for the record, when I build kernels here, I usually do:
1. I always build using vanilla kernels from kernel.org (not
distro-modified kernels).
2. I generally try to configure the kernel as flexibly as possible. So
I try to enable everything and configure as modules. The resulting
kernel therefore still isn't too large, and if there's something I later
discover that I need, then it's usually ready to load from a nearby
module.
Building everything as modules can of course result in a LARGE tree of
modules, but it's just disk space and these days disk space is cheap.
There's zero performance penalty in enabling something as a module that
never actually gets used.
