Oddly, the current busybox code (with the removed hunk) gets it right on a Red 
Hat 9 system, but does _not_ get it right on my 2.6 Ubuntu kernel.  If you 
list all interfaces on RH9 it shows the eth0:1, but doesn't on Ubuntu.

I have no idea what's up with that, but it appears to be a kernel thing.  
Remove that code snippet at least didn't break anything _new_...
