Ultimate Magneto question

[JLU Dude]

Not having read a lot of the Millar issues of Ultimate X-Men, I was wondering how much of of the "information" on the Ultimate sub-section of Mags' Wikipedia entry (http://en.wikipedia.org/wiki/Magneto_%28comics%29#Ultimate_Magneto) about his background is true?

Thanks in advanced.:)

Most to all of its true.
