+7. Load optional modules.
+
+If you are using loadable modules for the ppp or bsd compression then
+you must load them after the kernel has been started. The following
+relative order must be maintained.
+
+Sequence Module Description
+ 1 slhc.o VJ header compression
+ 2 ppp.o PPP driver
+ 3 bsd_comp.o BSD compression for PPP's compression protocol.
+
+You may elect not to load the BSD compression module if you desire. There
+is a controversy regarding a Motorola software patent and while it is
+believed that this code does not infringe upon the patent, it is however
+an optional component.
+
+In addition, if memory is a premium, do not run the BSD compression. It
+may take large amounts of memory (up to 2.6 meg) for high compression
+lengths to hold the compression dictionaries.
+
+Without the BSD compression module, the PPP driver will not accept PPP's
+compression control protocol for BSD compression.
