Macdennis from XboxHacker has posted some interesting informations regarding the X-Box 360 DVD firmware. Everything seems to indicate unique firmware per box at this stage. To quote:

Some new firmware facts!
A little birdie told me some information about a second dump of a Toshiba/Samsung TS-H943 DVD-ROM drive. In comparison with the dump made by darkfly, only 16 bytes are different. The difference is at offset 0x401A - 0x4029. Thanks little birdie for your great effort! A 16 byte difference was also the case with the GDR-3120 dumps.
All clues indicate that each x360 dvd-rom firmware contains an unique key. I couldn't match the key to a console id / serial or drive serial. It's probably an unique key used in the AES routine to encrypt/decrypt communication between console and drive. Something which is new for the x360.
Everything seems to indicate unique firmware per box right now.
