Trying to get HP Omnibook XE3 notebook network card to work

I have installed Suse Linux Pro 7.3 on a HP Omnibook XE3 notebook but the built in network card is not detected. According to 'lspci' it is an Intel 82801CAM (ICH3) Chipset ethernet controller. When we previously had RedHat 7.2 installed it detected and worked with the network interface fine. Under Windows 2000 the network interface is identified as "Intel Pro/100 VE" and seems to be using a standard 82557 driver. I have tried using modprobe to load the standard Intel Pro/100 driver but it fails saying the device does not exist. Any ideas? -- Gareth Blades
