Sorry for the delay in getting back to you on this, but my laptop and 
recent -CURRENT weren't playing well together.

The driver does not attach during the boot process and I see no messages 
with a verbose boot.  I'm not sure if this ever worked; I may have 
always loaded the module after booting.  In any case, I cleaned up the 
identify method and added some debug printouts (see attached diff). 
With those changes I see the following with a verbose boot:

smist: could not find supported isa bridge!

If I load the module after booting I see the following line (in addition 
to others):

smist: found supported isa bridge Intel PIIX4 ISA bridge

I can only assume that during the boot the call to pci_find_device is 
failing.  Any ideas?  Again, everything works fine if I load the module 
after booting.

Regards,
Jon
