I think there is a patch for the 1.2.13 kernel for IP aliasing, but before
getting that, consider if you could use the dummy interfaces for the same
job. You should compile the kernel with dummy interfaces as modules, reboot
using the new kernel, then:-

insmod -o dummy0 /lib/modules/1.2.x/net/dummy.o
ifconfig dummy0 <ip address> up
arp -s <local ethernet address> <ip address> netmask <netmask> pub
route add <ip address> dev dummy0

Of course, you can change the 'dummy0' above for various other addresses, or
add other options to the ifconfig/arp, but that's the general gist of how you
do it.
