Well, to answer my own question, I called VG today. It seems that when you transfer money in to them, either push or pull, the funds are immediately available for trading. However, there's a 10-ish day wait for being able to transfer the funds back out again. I never did find that documented anywhere, but they assure me it's in the fine print somewhere.
So I was hosed, as I need that money for settlement on a new house purchase. It would become available the same day as settlement, but that is too close for comfort for me. My solution, which they verified as being legit, was to withdraw $100K from my tIRA and transfer it to my bank. Then, when the original funds become available I can move them back into the tIRA. As long as it's done within 60 days of the withdrawal I won't incur any taxes.
I could have avoided all this by just paying for a wire transfer from PenFed to my bank, but then I'd have to turn in my cheap SOB card. Not going to happen.
