WRT the DMA access over FireWire it's but a bad response since it
doesn't get the point!
1. Drive encryption won't help against reading the memory.
2. The typical user authentication won't help, we're at hardware level
  here, and no OS needs to be involved.
3. The computer is up (and running; see above), no hibernate or sleep
  is involved here.

So on a freshly-booted system with drive encryption you can read
whatever you want on the disk? 

4. Group policies can be circumvented, even by a limited user.

What he says is that some group policies, not including system-wide
security settings, maybe circumvented, even by a limited user.
