Yes.

I'd say it would be used frequently, but short lived.

Yes, very custom.

Actually, not sure, I've always enabled that.

I wanted to beable to query battery life on laptops that I use this on. I
can remove it I think, all ACPI that can be a module is. I don't think it
works that way though. I'll have to check it on a laptop.

Yes, however, pcmcia is modular.

We have some old ISA cards that support PNP (3c509 comes to mind)

All SCSI is a module, these I assume are just capabilites in the modules.

Couldn't find a configure option to disable this. It caught my eye too. I
don't have gameport in input configured.

All of those or DUMMY_CONSOLE?

All USB are modules, NTFS is a module (yes I need it)

Crypto is required by one of the wireless drivers (MADWIFI I believe)

Nothing, I wanted to see if zImage would be smaller. As others have stated,
it's not. However, I did not know this.
I do appriate your time in helping me. I'm real close to getting this on a
single floppy (if I formatted to 1.7mb, it would be easy. I know some of
our systems that I would need this on can't use these). One goal is to use
the same kernel for all booting.
