Umm - whoever said something about stability doesn't know what they are talking about. You can add (alias) many IPs to a single card - one of the great features of unix/linux systems.

I have aliased as many as 20 ips to a single PCI card before. This is usually done on firewalls that have a number of servers on a private lan. The public IP's are NAT'd to the private ones using something like natd or ipnat, working in conjunction with a firewall package.

I add aliases to interfaces in freebsd like this:

# ifconfig interface alias ip_address subnet_mask

'man ifconfig' will give you more detail.
