Found under tools/module-init-tools. These are not (for now)
automatically built and installed when the kernel is built.

To build and install, enter the module-init-tools directory,
and do the following:

   [ 1 ] aclocal -I m4 && automake --add-missing --copy && autoconf
   [ 2 ] ./configure --prefix=/ --program-prefx=lcd-
   [ 3 ] make
   [ 4 ] (sudo) make install

This will install the patched /sbin/lcd-modprobe and /sbin/lcd-insmod,
as well as the other init tools that were left untouched. The
user mode helper will use lcd-modprobe to load the module.

The man pages won't install on emulab (since /share is read only).
You can specify a different man dir via configure if you wish.

After installation, you should then be able to successfully run a
kernel module inside of an lcd, via lcd_create_as_module.

The only changes to init tools are in modprobe.c and insmod.c; only
the changes in modprobe.c are of interest (lcd-insmod is not currently
used/needed). Instead of doing the Linux init_module system call,
lcd-modprobe does an ioctl call to the LCD driver (hence, the LCD driver
must be loaded), with the bytes of the module, its size, and command
line options.
