hda_codec: Unknown model for ALC662,  How to check or get driver?

Ubuntu Server 7.10
Mother Board: GA-G33M
Northbridge G33 Southbridge ICH9
Realtec ALC662 Codec HD Audio integrated

First install of Ubuntu ...
On boot I get the following message
kernel: hda_codec: Unknown model for ALC662, trying auto-probe from BIOS...

I did a search and a few old messages made reference to this codec and how one should get the latest drivers.

Newbie question: Where does one best get these drivers? How does one install these drivers?
I found a site:
http://www.realtek.com.tw/downloads/...3&DownTypeID=3
These are the Linux drivers, do they work for Ubuntu Server?
How can one check which (if any) drivers and versions are installed?
