Ok, there are Continuum Spoilers here. Well.. One TINY TINY spoiler, but I don't intend to use tags so bugger off if you don't want a MINOR spoiler from Continuum...
Your own fault then.
Ok basically near the end of Continuum Teal'c uses a small hand device on the gate in Russia to not only dial out but to power it as well. (I know after all that, how undramatic?). In any case, the way I see it, that scene has pretty much solved the supposed "plot hole" surrounding the way in which Apophus dialled out of the Gate Room at the start of Children of the Gods.
So.... hurrah. Rest easy, get some sleep, have a beer.... ah whatever.
