Apparently, though unproven, at 17:15 on Monday 24 January 2011, Amar Cosic 
did opine thusly:

You have aliased three additional IPs to a NIC. You cannot add routes to those 
aliases, only individual IP addresses.

You will either have to come up with a routing scheme that routes_eth0 fully 
satisfies or pony up the cash for three NIC cards.

I'd go for option 2 - NICs are dirt cheap.
