+USING THE NEW PPP KERNEL DRIVER
+
+As of kernel version 2.3.13, the development series of kernels contain
+a new kernel PPP driver, rewritten from scratch by Paul Mackerras.
+This package supports the new driver, although it doesn't include the
+source for the new driver.
+
+The new driver is divided into two files: ppp_generic.c and
+ppp_async.c.  If you compile PPP as a module, you will get two
+separate modules, called ppp_generic and ppp_async.
+Another module ppp_synctty is used for synchronous tty devices
+such as high-speed WAN adapters for leased T1/E1 lines.
+
+To talk to the new driver, pppd needs to be able to open /dev/ppp,
+character device (108,0).  If you are using devfs, the device
+filesystem, the /dev/ppp node will automagically appear when the
+ppp_generic module is loaded, or at startup if ppp_generic is compiled
+in.
+
+If you have ppp_generic as a module, and you are using devfsd (the
+devfs daemon), you will need to add a line like this to your
+/etc/devfsd.conf:
+
+LOOKUP		ppp		MODLOAD
+
+Otherwise you will need to create a /dev/ppp device node with the
+commands:
+
+# mknod /dev/ppp c 108 0
+# chmod 600 /dev/ppp
+
+If you use module autoloading and have PPP as a module, you will need
+to add the following to your /etc/modules.conf or /etc/conf.modules:
+
+/dev/ppp	     ppp_generic
+alias char-major-108 ppp_generic
+alias tty-ldisc-3    ppp_async
+alias tty-ldisc-14   ppp_synctty
+
