You should not reserve an address for an interface on your DHCP
server and at the same time attempt to give it a specific address.
It will get one anyway but in a DHCP lease.  Maybe this is causing
an appearance of this "ghost" eth1 interface which you are talking
about?  

In any case if an interface is configured to use DHCP then any
specific address assignments in its configuration file are ignored
(or at least they should be).

OTOH I recall that on some occassion NetworkMangler crashed on me
and later it was so entangled in its own junk that it could not find
a way out.  That will be that bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=413281
See in particular comments #10 and #11 how I eventually forced it to
find correct interfaces as otherwise NM was terminally lost.  I have
no idea if this still applies.  In case that it does then reopen the
bug.
