Right, had a bit of time to consider this, do a bit of googling, and also check the Daily Mail article in person.
As has been pointed out, they've spelt both names wrong - it's Berge Larsen who's the big cheese at DNO and reputedly bankrolls Pools. That immediately casts some doubt on the rest of the article. For starters, how does Allen know Larsen? There's nothing been said before, and Allen's been in charge at Sheff Wed for long enough - why wait until now, when news of a Norwegian Oil Tycoon interested in investing would have got the fans off his back a couple of years back when Bates was stalking them?
Next, most of the current Internet stuff refers to this mystery Chinese Casino owner. Kev's in a good position to know about the situation over there, and it may be that we're talking someone from Macau rather than China itself. Allen is a Casino owner himself, so that answers partly how he might know those people - and they've been seen at a match, unlike Berge Larsen who I believe has only seen Pools play rarely.
One interesting thing from the DNO site: Berge Larsen did his degree (Chemical Engineering I think) at Newcastle. Therefore there is a link with the North-East... anyone see a Norwegian student at the vic in the 70s?
My Norwegian is non-existent so most of the stuff about Mr. Larsen (including on the Norwegian version of Wikipedia) is unintelligible to me. I can't even tell you whether he is genuinely the driving force behind the IOR-Pools linkup, although it seems likely. However, we do have a 10 year track record with our current owner(s) where considerable investment has been made on and off the pitch and we've had more success than in the other 90 years of our existence combined. That doesn't mean it will last forever (what does?) but there have been plenty of opportunities in that time to get involved with other clubs - Leicester for example. Yet IOR are still here, Uncle Ken is still paying the bills, and there's nothing concrete to say that it's not going to continue....
