AT-1500FT PnP card, FreeBSD-5.4R-p1 and lnc(4) problems

I am trying to make a network card work with lnc(4) device.
The card is an AT-1500 PnP Ethernet Adapter based on PCnet(TM)-ISA II
chip from AMD (AM79C961AKC) which is supposed to be supported under lnc(4)
driver. The card has both a 10BaseFL(ST) and 10BaseT port.

After adding the card's pnp id to the lnc_pnp_ids[] structure I am getting
the card recognized and attached but the chip and MAC address are wrongly

Both the Ethernet Address and ic type are wrongly detected!

Any help will be appreciated!
