Full disk encryption: Key on USB storage device

I want to encrypt my Netbooks HDD.
If I understand
that is possible with the Alternate install CD.
But what I miss: Is it possible to put the key file onto a USB stick so
that it is loaded automatically from there at boot time? Long time ago,
I looked at the Gentoo initrd script, which apparently supports this.
A bit more sophisticated: Is it possible to put the whole boot partition
including the key file onto a USB drive?
I also found https://wiki.ubuntu.com/SmartCardLUKSDiskEncryption, which
sounds nice. Are there such smartcards in the form of a self-contained
USB device which I can put on my keyring?
