Kernel How-To

Do any of you know the ways to take out only the "access point kernel" from the main Linux Kernel. In my case here, I installed the Madwifi + Hostapd. Meaning to extract some portion of the kernel from the main kernel.

Then, this so called "access point kernel" will become a standalone kernel, that can be loaded-in and boot from other media, like compact flash and Bootable USB pendrive, etc. By this way, I can build another access point using small mini motherboard with DC or AC supply.

you want to build a AP, right?
just configure the kernel as minimal as possible with the AP related features you need.
if you want to have a slim system, think about a libc with smaller footprint than glibc, maybe uclibc or dietlibc.

no, i don't have a reference.
the only advice i can give you is to remove all drivers, filesystems and stuff you don't need.
and you can play with preemption model and check what performs better.
