Sorry, this part is from module(9). For module(7), there is a mention in
the CAVEATS section:

  If an attempt is made to boot the operating system from a file
  system for which the module is not built into the kernel, the boot
  may fail with the message ``Cannot mount root, error 79''.  On
  certain architectures (currently, i386 and amd64), one may be able
  to recover from this error by using the ``load xxxfs'' command
  before trying to boot.  This command is only available on newer
  bootloaders.


Wording seems a bit redundant, so I condensed this into:
