From inspection, the only routines actually used by the FreeBSD
driver from the (proprietary) nVidia object file are ADAPTER_OPEN,
ADAPTER_ReadPhy, and ADAPTER_WritePhy; it could well be that
replacement, non-proprietary versions of these could be written
from the information in forcedeth. In addition, I've sent mail to
the authors of the documentation used to produce the driver, but
haven't actually gotten any information back yet.

Presumably, since the PHY goo is in the proprietary .o, it does.
(I only have an nForce2, so no gigE for me.)
