-Os is preferred for low memory systems.

I just killed some processes and arrived to bare system 64MB.
Now just sshd, bash and agetty are showing in ps aux as real processes.
The other are kernel processes.
The kernel is pretty lean. Should I expect 64MB as the initial system memory use?
Can I lower it?

Thanks,
