Let me guess, you both use RedHat-5.x? That's a problem of linuxconf.
When you run ifup the following command will be executed:

linuxconf --hint ipalias eth0

This command says that no ip aliasing is present, although it really is:

[root@planetzork /root]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:00:B4:32:4C:87
inet addr:195.37.122.246 Bcast:195.37.122.255 Mask:255.255.255.255

eth0:0 Link encap:Ethernet HWaddr 00:00:B4:32:4C:87
inet addr:192.168.1.1 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
Interrupt:10 Base address:0x280

Try:

ifconfig eth0:0 ip1 ....

Well, yeah ... I suppose there's no point in getting greedy, is there?
