Onboard network adapter not connecting

2010.1 newly installed

Ethernet card: NetLink BCM57788 Gigabit Ethernet PCIe

No driver was available for this card in 2009.1 so I had to use a
Belkin USB adapter which registered as eth0.  Research on the net
indicated that the netlink card had support in later kernels so I
tried it with 2010.1.  Drakconnect says it is trying the tg3 module
but fails to connect to the internet.  So, back to the USB adapter,
which works fine.  The Netlink card is assigned to eth0 and the Belkin
adapter to eth1.  Does anyone have experience of the Netlink card or
any suggestions on how to activate it?

These are extracts from lsmod:

eth1 is a Belkin F5D5055 Gigabyte USB using the asix module.
