panic with HEAD

[Matthew Dillon]

    Ok Steve, update your kernel sources again just to sync up the patch
    I committed to if_wi (which is the same one you already have), and 
    then try this patch on top of that.

    The issue is that the cardbus code's handling of BUS_SETUP_INTR ignores
    the serializer passed into it from IF_WI.  I think this will deal with
    the case properly but I can't test it.
