Re: em0: Unable to locate IO BAR ( two 82542 cards )

Sigh, I changed the logic of what adapters try to map the IO
BAR because only older adapters use it, but now that I look
at the shared code, it turns out when you get to the oldest
ones, aka 82542, they dont do it either. The code used
to make ALL adapters except the 542 try to map it, I
could revert to that, but let me think about this a bit, I
will check in a fix for it by tonight ok?
