   The bug was in the PCI support. The PCI support was not included in
FreeBSD 2.1.6. FreeBSD 2.1.6 and 2.1.7 are bug-fix releases and generally
do not include new features or device support.

   Yes, there was a bug in the original PCI driver. The fix is attached.
FreeBSD 2.1.* does not have support for the PCI driver, however. This is why
I provided it to you seperately. Only FreeBSD 2.2 and newer have the support
for the PCI Cyclades Cyclom-Y card.
