Patch to support drivers compiled into the kernel

[Bill C Riemers <briemers redhat com>]

Currently, NetworkManager ignores any network driver that does not have
a loadable module associated with it.   This is a problem, when the
network driver has been compiled directly into the kernel.  This is
typically done for coLinux, and other environments where a loadable
module network driver is not supported.

The following patch marks the driver for such devices as "<kernel>", so
that NetworkManager will not ignore them.   However, NetworkManager will
still ignore network devices which do not have a driver associated with
them and is not built-in as part of the kernel.

Note: I created this patch on Fedora 10, against the 0.7.0-1 version.  
Please let me know if I need to do a git checkout and rebuild this patch
against the current code base.
