Adding real time modules to pathpilot possible?

I would like to add a couple of modules such as "mux4.ko" to pathpilot. How would I go about getting or creating these files to work with pathpilot?

2 ways i can think of since pp is based on 2.6.0~pre you can find a CD for that and use the modules from it or build your own as needed.

second is get the PP source disk from Tormach (cost me $10) and make a dev environment from it so get modules.
thats what I did for the some modbus drivers

I tried doing this with 2.6.13 with classic ladder following this guide...

forum.linuxcnc.org/pathpilot/31483-classicladder-in-pathpilot

No joy. Is there a specific version required?

Yes, PP was built with 2.6.0-pre I mentioned above. realtime modules as I understand are linked to kernal and rtia they are built for

FWIW - I found 2.6.0-pre searching with google

Sorry I am very green when it comes to linux. I found the 2.5 live dvd with lucid 10.04. I could not find a 2.6.0 - pre version. I installed 2.5 but I am having troubles updating that to 2.6.0 - pre. I updated all the sources on the install so it will update via the package manager. 2.6.13 is the version it gives me. I assume there is a way to upgrade to the specific version via the terminal. I am having trouble locating that. Maybe you can help? Sorry I am learning

Everything I have found points me here...

www.linuxcnc.org/docs/2.6/html/common/Updating_LinuxCNC.html

That only allows the latest 2.6 from what I can tell?

Is this where I would look?

Well, I have a 9x20 lathe I converted over from manual to Mach3 to pathpilot. (so this is a big step up) I have everything working but my MPG and my physical cycle start / feed hold buttons. I really need mux4 for the MPG. The buttons I will do in hal with what I have to work with. I have used classic ladder before and its a great addition for when I add a tool changer. Now... The reason I am in love with pathpilot is the ease of use. Its straight forward. I have 2 sons that want to learn to use it and I feel with this interface I can get them up to speed fast. I love to learn as well and this has been a big learning experience. I figured out how to get my old elo touch screen going that was serial by turning on the serial ports they turned off and editing a few files to make it all work. Even the calibrate feature in pathpilot works. So I am way too close to give up now Also someone else reported that classic ladder is working so I wanna get it working on this machine as well for when the time comes. Any help is much appreciated.
