Even if I did it would not help.  Presumably NetworkManager works with a
kernel that uses external kernel modules.  The problem I have is that it
is not working with a kernel that has the drivers compiled into it.

It seems as if the interface is present, it is just that NetworkManager
is not finding it.  Presumably, since "The point of NetworkManager is to
make networking configuration and setup as painless and automatic as
possible." it should find any network devices if they are present.

In my case it seems as if NetworkManager is not following the symlink:

>>> ls -la /sys/class/net/eth0/device/

So if I look at /sys/devices/pci0000:00/0000:00:1c.0/0000:01:00.0 I get:

ls -la /sys/devices/pci0000:00/0000:00:1c.0/0000:01:00.0

Which seems to be what you were looking for.
