Start-up virtual interfaces

I put some virutal interfaces in my startup networking config and now they don't show up when ifconfig is run I think they're being created with the ip command. My /etc/conf.d/net looks sort of like this (IPs are changed):
# cat /etc/conf.d/net
config_eth0=( "88.85.87.80 netmask 255.255.255.128"
"88.85.87.82 netmask 255.255.255.128"
"88.85.87.88 netmask 255.255.255.128"
"88.85.87.85 netmask 255.255.255.128")
config_eth1=( "10.1.1.1 netmask 255.255.128.0"
"10.10.1.5 netmask 255.255.255.0" )
routes_eth0=( "default via 88.85.87.89" )
ip addr show lists the ip addresses but not ifconfig, is there a way to change this so ifconfig will work, and if there is, is there any reason why I wouldn't want to do that?

Which one is virtual?

Maybe you meant 'subinterfaces'?

Looks like he wanted:

eth0 88.85.87.80 netmask 255.255.255.128
eth0:1 88.85.87.82 netmask 255.255.255.128
eth0:2 88.85.87.88 netmask 255.255.255.128
eth0:3 88.85.87.85 netmask 255.255.255.128

My understanding is that 'ifconfig' cannot show you what you want. It doesn't have the brains to do it. Only 'ip addr show' can show you the extra IPs. This is the 'expected' behavior.

On my Web Server it works fine:

wserver ~ # ifconfig
