Log Message:
Add a table of known-64-bit DP83820-based cards.  Use this table
to enable 64-bit data transfers on 64-bit cards when plugged into
a 64-bit slot.  Right know the Asante GigaNIX is listed in that
table.

Sigh, there is an EEPROM bit that can be used to detect 64-bit vs
32-bit cards.  Unfortunately, at least 2 vendors of 32-bit cards
fail to clear the "DATA64_EN" bit in the EEPROM, which causes the
card to lose badly, because it still manages to detect that it's
plugged into a 64-bit PCI slot.  Yay, stupid hardware vendors.
