I managed to manually merge the mppc patch into kernel 2.6.24 and ppp-2.4.4 using a modified version made for 2.6.23 from Devil Linux. And I updated the kernel26 and ppp PKGBUILDs for Arch Linux to use them.

I had a VPN with mppc running and could comfortably ssh to the machines on the network, but I am unsure about the stability.. this has been extremely little tested, so take care..
Usage is explained on the official site for the original patch: http://mppe-mppc.alphacron.de/ usage of PPTP on Arch Linux in the wiki. For Arch you probably need ppp-mppe and pptpclient.

Modified patch for kernel and ppp:
linux-2.6.24-mppe-mppc-1.3.patch
ppp-2.4.4-mppe-mppc.1.1.patch

Patch for the source for the Arch packages in ABS:
kernel26-arch-mppc.patch
ppp-2.4.4-arch-mppc.patch

Patched source for the Arch Packages (extract and run makepkg -c and pacman -U on the result):
kernel26.tar.bz2
ppp.tar.bz2

Packages for Arch (pacman -U):
kernel26-2.6.24.3-3-i686.pkg.tar.gz
ppp-2.4.4-6.i686.pkg.tar.gz

mppc is patented and if you feel like you should have a look if you are allowed to use it.

After changing from Ubuntu to Gentoo I lost support for mppc, and the patch only works for kernels up to 2.6.13. I finally found that devil-linux has created a patch for the 2.6.23 kernel that replaces the native mppe patch.

$ cd /usr/src/linux
$ wget http://devil-linux.linjection.org/devel/sources/1.3/linux-2.6.23-mppe-mppc-1.3.patch.bz2
$ bunzip2 linux-2.6.23-mppe-mppc-1.3.patch.bz2
$ patch -p1 < linux-2.6.23-mppe-mppc-1.3.patch
$ make menuconfig

Go to Device Drivers –> Network Deevice support:
Check the PPP options, you will see the option:
Microsoft PPP compression/encryption (MPPC/MPPE)

Then compile/install as usual, and you will have the module: ppp_mppe_mppc available, replacing the ppp_mppe.

Unfortunatly NetworkManager refuses to compile right now.
