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.
