Full HDD encryption (including swap space and hibernate file) and
powered down or hibernated (s2disk) machine is the only way to go.

It is possible (assuming Linux system with LUKS with minor modification
of the kernel) to chroot to ramfs, drop the encryption keys, suspend the
system to RAM and ask for the keys after resume, the rest of the RAM is
still possibly readable by an attacker.
