Well it seems like the Right Thing To Do anyway to make it all 64bit clean ;-)

Can we not print them onto the console if they're normal then?

I think the card took itself offline at this point, so it smells like a bug. That's only been happening recently though (I've only noticed in the last week from a year or two of use).

OK, will try to grab that.

Sure, send me the patch, these boxes bring out races like dying rich aunts bring out friendly relatives. And I have a cabinet drawer full of starfire cards ;-)
