 I don't know, as I no longer have a machine running day-to-day that is a
 good test case.
 
 After submitting this, I resigned to the fact that no one was interested,
 probably rightly so, as the driver is probably not the best place to fix
 what is really a BIOS PCI bus initialization issue, although there were
 other drivers, at the time at least, that did this, too.
 
 I maintained a local kernel patch for a little while, then realized it's
 really just as easy to do something like
 
      pciconf -w -b pci0:9:0 0xd 0x60
 
 if rc.local, and that's what I did for a long time. In the last few
 months I have upgraded the machine that was the test case for this and it
 now has an Intel NIC.
