I'd like to copy Bill Paul on this, but am gun-shy ;-)

I found an older Xircom CardBus Ethernet II adapter that worked.
I know it's not a bad adapter because:

  1) I've two of them (both shrink-wrapped and brand new)
  2) They work under Windows on the same laptop(s).

The older Xircom is identically marked - CBE2-100.  I can
see no physical differences between the older Xircom and the
two newer Xircoms.

To summarize, these are the cards I have tried:

  (A) - Xircom RealPort CardBus Ethernet II 10/100 + Modem 56
        -- works

  (B) - Xircom CardBus Ethernet II 10/100, CBE2-100, old
        -- works

  (C) - Xircom CardBus Ethernet II 10/100, CBE2-100, new, qty 2
        -- neither work

When I boot verbose, the only difference I see between (B)
and (C) is that (B) has a powerspec of 1, while (C) has a
powerspec of 2:

  (B) powerspec 1  supports D0 D1 D2 D3  current D0
  (C) powerspec 2  supports D0 D1 D2 D3  current D0

Full boot messages available on request.

 -- (B) Old Xircom, works
