No, thats not the problem. 

The problem is that attempts to open "/dev/ppp" will fail without
KMOD, because the vfs layer (devices.c) will *not* call
request_module() to load the the module for char-major-108 (the code
is #ifdef'ed out).

Thus, there is no device to use. Its not a compile time problem, its a
run-time thing: modules that depend on dynamic "creation" of 
major number devices via KMOD will never work without KMOD.

I suspect that ppp is not the only driver with this problem, BTW.
