The Knowledge Base shows that Vcc (0.9V), and Vccp (1.8V) should come up before Vcceram (0.9V), Vccr_gxb (1.8V), and Vcct_gxb (0.95V). This requires splitting the voltages and adding power switches to sequence the voltages. Is this required?

What are the ramifications of not sequencing these power rails? Does it cause configuration issues, functional problems, or long term reliability issues?

Intel recommends power sequencing... If you do not respect them, correct behaviour is not guaranteed and the causes of the dysfunctions may be difficult to detect.
