Intel Atom Disk Encryption Performance

Encryption is interesting, but don't think it is unbreakable. Suspend can lead to new attacks:

Also when the pc is accessable to somebody with a live system the initrd can be modified - as this is not encrytped. And when you do that, you could store the key where you can find it when you come back...

True, although I guess you could boot from a usb-stick or a cd that you always carry with you, or otherwise can be sure has not been tampered with.

But it's actually very hard to defend against somebody with repeated physical access to your system. They could always install a hardware keylogger even if your software is unbreakable.

Yes, keyloggers are also possible. Just a bit harder to add when you have got a laptop. For standard pcs the keyboard could be modified/replaced more easy.
