there is no official spec for the utilities to load modules.  whatever module-
init-tools supports, that is the "spec".  as such, i dont think it makes sense 
to attempt to integrate into ltp.  otherwise we waste time attempting to keep 
two distinct and unrelated trees in sync with each other and having ltp try 
and support a myriad of module-init-tools versions.  my head hurts thinking 
about it.  the testsuites here validate the *module-init-tools interface*, not 
the *linux module syscall interface*.

in fact, i dont think any of the module-init-tools tests use any kernel 
related function (i.e. they dont actually poke the kernel).  this would make 
sense to develop in ltp: functions that actually tested the module related 
syscalls.  the ABI there is static and part of the kernel.  then we can even 
do things like try and crash the kernel with bad arguments/modules/etc...  if 
running `make check` in module-init-tools crashed my kernel, i'd be seriously 
pissed.  if ltp did it, i'd be happy because ltp is doing its job.
