If you want multiple IP subnets on a single ethernet network, you'd be 
better off using VLANs, even cheapo switches can handle that, then your 
linux box with a single NIC can have VLAN sub-interfaces e.g. eth1.1 on 
192.168.0.1/24 and eth1.10 on 192.168.1.0/24

If you don't want VLANs you *could* use a NIC alias so that e.g. eth1 is 
on 192.168.0.1/24 and the alias eth1:2 is on 192.168.1.1/24 ... but why?
