I don't see why you need a whole kernel RPM, in relation to PPTP issues.

All you need kernel wise is an mppe module, and a ppp/ppp_generic module 
which allows 64byte parameter blocks (which requires a recompile).

You could remove the ppp/ppp_generic module from the mix if either the
standard kernel allowed 64byte parameter blocks, or the mppe module
interface passed a pointer to NT hash rather than the NT hash to the
kernel. The module could then do a copy from user to kernel space to get
hold of the hash, which is used as to initialise the encryption key. So 
all you'd need is an mppe module.
