I agree, the vulnerability is specific to MSCHAP-v2.  I know nothing
useful about EAP, sorry.  I don't know if anybody has it working with
PPTP.  Yes, MPPE depends on MSCHAP-v2, I don't think it can be made to
depend on anything else, but that's a matter for the pppd guys, in
pptpd land we just ask pppd to do it.
