Preparations for Sam's incredible iMessage fix!!!

Sam blogged about why iCloud/iMessage didn't work with a self compiled
kernel. She did this, long before anyone even had a clue, after she
figured out that the Apple kernel includes undocumented changes. Not
only that. She also figured out how we can make it work again, and this
is step one of her findings.
Always inject a board serial/type, which is required to fix iMessage breakage
