No, he will not :) I have just bog-standard one network per NIC, ergo eth0
and eth1. Of course, it wouldn't be a problem to quickly configure one NIC
with two IP addresses and I would/will gladly do it if you need it.
Only, I have SuSE 7.1, and there's no such thing as ifcfg-ethX, there
isn't even an /etc/sysconfig - all the crap RH & Co. keep in
/etc/sysconfig is crammed in one single, heeuuuge /etc/rc.config file over
here, but still not huge enough to carry as much information as I can see
in your ifcfg-eth's.
I'd say I can see a couple of funnies here:

Well, in case it's any help here's what:
19:42:30 root@www:~ # ifconfig eth0:1 10.0.0.7 netmask 255.255.255.0 up
gives me concerning eth0 and eth0:1
eth0 Link encap:Ethernet HWaddr 00:00:CB:60:44:D2
inet addr:192.168.0.1 Bcast:192.168.0.255 Mask:255.255.255.0

I'm surprised to see that ifconfig obviously got the broadcast of eth0:1
wrong, as this should be 10.0.0.255. I think.
I checked the routing tables while I was at it, and it does its job:
Destination Gateway Genmask Flags Metric Ref Use Iface
172.19.89.138 0.0.0.0 255.255.255.255 UH 0 0 0 ppp0
192.168.0.1 0.0.0.0 255.255.255.255 UH 1 0 0 dummy0
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth1
10.0.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
192.168.0.0 0.0.0.0 255.255.255.0 U 0 0 0 eth0
0.0.0.0 172.19.89.138 0.0.0.0 UG 0 0 0 ppp0
- it has added a route for 10.0.0/24 via eth0, which is nice.
Hope this helps...
Cheers
