The link monitoring should be unrelated to HAL/udev/DBUS.

It is does via netlink sockets, at a low-level.  See
src/nm-netlink-monitor.c.

Does your wired device work otherwise on return from resume?  It could
very well be that NM is not detecting it properly and the link detection
is just a fallout of that.
