Things are definatly different in many places. I hope getting the hang 
of the Debian way doesn't prove to be too stressful.

I just added the eth0:0 entry to /etc/network/interfaces:

[copy]

auto eth0
iface eth0 inet dhcp

auto eth0:0
iface eth0:0 inet static
   address 192.168.1.98
   network 192.168.1.0
   netmask 255.255.255.0
   broadcast 192.168.1.255

[/copy]

After issuing an ifup command, I had:

eth0      Link encap:Ethernet  HWaddr 00:01:02:26:0A:0A
         inet addr:192.168.1.8  Bcast:192.168.1.255  Mask:255.255.255.0

         inet addr:192.168.1.98  Bcast:192.168.1.255  Mask:255.255.255.0

Maybe some parameter in your settings for eth0:0 is incorrect.
