The patches patch pppd, which then patches the kernel. So you do use the
ppp_mppe module
$ lsmod|grep ppp
ppp_deflate     40484   0  (autoclean)
ppp_mppe        13584   0  (autoclean)
ppp             20012   0  (autoclean) [ppp_deflate ppp_mppe bsd_comp]
slhc             4328   0  (autoclean) [ppp]

>(char-major and compress-18)?  I am able to turn off compression on win2000

alias ppp-compress-18 ppp_mppe  <===
alias ppp-compress-21 bsd_comp
alias ppp-compress-24 ppp_deflate
alias ppp-compress-26 ppp_deflate
#alias char-major-108 ppp_generic  this is for kernel 2.4.x
alias char-major-108 off  <===

I think this is because it cannot load ppp_mppe since your modules.conf
lacks the alias.
