Are you saying that these two documents

33610 Rev. 3.48 December 2011
41788 Rev. 3.10 December 2011

both wrong? For fam 0xf it may be that we can set a lower bound for
pre-NPT ones if those indeed are unaffected (but we'd like to be sure
this is the case) - that would appear to be all with a model below 0x40.

Please clarify.

Jan
