We should be using vnode struct addresses instead of major/minor
numbers internally to the kernel.

For boot-critical drivers, the correct method is not to assign a
particular lexical offset to the critical drivers (since this
implies a lexically based lookup, and we want to kill that).

Major and minor numbers need to die.
