I assume you have ppp as a module, not compiled into the kernel.
ppp_init() and ppp_first_time() get called when the module is loaded.

You need to `rmmod ppp' to unload the ppp module, then do `insmod
ppp.o' to load your new version of the module. `lsmod' will show you
which modules are loaded. If the module gets loaded automatically, it
will get unloaded after a period of inactivity.
The "can't locate module ppp0" message happens when pppd tries to do
an ioctl on ppp0 to see if the kernel has ppp support. You can have
the ppp module loaded but no ppp network interface units existing.
