Note the origin (hi FreeBSD!) of a couple clever bits of Xbox 

initialization code. No functional changes.

/*
* From Rink Springer @ FreeBSD:
*
* Some XBOX loaders, such as Cromwell, have a flaw which cause the
* nfe(4) driver to fail attaching to the NIC.
*
* This is because they leave the NIC running; this will cause the
* Nvidia driver to fail as the NIC does not return any sensible
* values and thus fails attaching (using an error 0x5, this means
* it cannot find a valid PHY)
*
* We bluntly tell the NIC to stop whatever it's doing; this makes
* nfe(4) attach correctly. As the NIC always resides at
* 0xfef00000-0xfef003ff on an XBOX, we simply hardcode this address.
