Sorry, I was just babbling without checking.  There are 6 BARs, but
that doesn't change the fact that the SonicVibes card wants
two additional I/O regions which are programmed at addresses 0x40 and 
0x48 in confuguration space.
So the basic problem remains.

As has been pointed out, even delaying the allocation until after
all other attachments have been done will guarantee that you
can find free I/O space, but it's the best I've been able to come
up with.
