As far as the security chip... I have found a similarity between the mem card and wireless adapter in the image below.
LMFAO!! You spotted the Crystal! It's not a security chip.... It's part of the clock generator.
EDIT: A couple of interesting points for discussion...
1) That top left chip on the 360 photo is apparently (I can't tell 100% from your photo) an EEPROM. That would be interesting to read...
2) The memory chip itself, has anyone thought about stacking, or somehow adding a sub PCB for extra RAM.
EDIT: Actually, it might not be the clock crystal, but the crystal for the 2.4Ghz wireless signal, but it's nothing to do with security and it is a crystal!
