Bloody Ubuntu and network interfaces grrr ;)

[FirebarUK]

I've just changed the NIC on my ubuntu server and for some stupid reason ubuntu (ubuntu-server) 8.04 doesn't auto detect new interfaces very well.

I've tried the following to no avail:

1) edit /etc/modprobe.d/aliases and adding 'alias eth0 pcnet32'
2) edit /etc/modules and adding pcnet32
3) lsmod to ensure the module is loaded
4) ensuring /etc/network/interfaces has eth0 as DHCP in there.

The annoying thing is SOMEWHERE it's still keeping reference to the old adapters MAC address and I can't find out where!

This is doing my head in. If I were using another distro it would run Kudzu or something to autodetect and reconfigure

Can anyone help?

Thanks.

Stuff it, just made the interface eth1 instead of eth0. How annoying.

File doesn't exist, this is quite an old mechanism is it not? How would I do it on a vanilla ubuntu box (without installing ifrename) ?
