When I bought my Deluxe in May 2003 both versions were on the dealer's shelf. I'd already read about the rev 2.0 so looked carefully at the boxes - all said "A7N8X Deluxe", "333MHz FSB" and "Dual-Channel DDR 400" but some of them also had a 1x2" yellow and red sticker that said "400 FSB Ready nForce2 SPP(Ultra 400) Chipset".
Which one would you have picked up? I got one with the sticker.
ASUS caught a tremendous amout of flak from people with the older boards so it's quite possible they released the rev 1.04/up 1008 BIOS with a neutered 400MHz ROMSIP to help achieve 400MHz operation and quiet the uproar. People saw DDR 400 and assumed FSB 400 so no wonder they were mad when the 2.0 soon came out, especially if they got a 1.x board in Spring/Summer of 2003; you could rationalize it more if you got a 1.x board in 2002. Of course there was an overlap of old and new stock for a few months and anyone would be mad if they got the older board.
What would be interesting is whether performance BIOSes like Trats still allow you to run at 400MHz or faster (with an aggressive 400MHz ROMSIP). I can run the Trats 1008 rev 2 mod at 1T over 220/440MHz on my rev 2.0. You'd definitely need the Ultra 400 Northbrige to do that on a 1.x. Hopefully you're right that later 1.x's do have it. No fun but you could pull the heat sink to be sure.
Apologies to the original poster, we sure have let this thread get off topic!
