Could you please be a bit more specific with your question? Which distribution are you concerned with using this on (as different distributions handle module loading and unloading slightly differently)?

Typically, you shouldn't have to worry about unloading modules, by hand, at power-off.

It is for an Embedded linux based system.The system is not having a distribution,it is having redboot bootloader,customized ramdisk and zImage.

Well, if you want to manually insert kernel modules on boot, the place I would suggest to do it would be in "/etc/rc.local". Just add "/sbin/modprobe kernel_module" for each kernel module you would like to load at boot.

i am having just /etc/rc.sysinit file, i have already put them in rc.sysinit file as

insmod /lib/modules/2.6.20-4/misc/module1.ko
insmod /lib/modules/2.6.20-4/misc/module1.ko

Is it fine?

That's fine, but instead of using "insmod" I would use "modprobe", and I would supply the full pathname just for safety: "/sbin/modprobe".
