I did a bit more snooping,  and find that the bus_alloc_resource() for
IOPORT and IRQ succeed, but then aic_probe() fails.

aic_probe() pushes 16 bytes on the  stack, and then reads them back to
make sure they are the same [1].  This fails on the 2nd read. i.e. 

     outb 0, 1, 2, ..., 15 
     inb  0, 0 (expected 1 here)

I don't know what  it means, but I thought someone  else might :-) I'm
off to a meeting for a couple of hours, but wanted to post.

Cheers,

[1] The code says stack, but it looks like a FIFO to me :-)
