it does not make keyloggers useless, only requires slightly different manipulation
to the system.

You get the best safety if you have encrypted root and swap and boot off
a CD which contains your kernel and ramdisk. There is no keylogger unless
you did burn it on the CD.

Guaranteeing the integrity of the boot media is extremely important and
afaics only physical security of the media helps here.
