Note that you need, specifically, a 2.0.36 kernel, to be compatible with
the special RT patch.

OK, then get it from the CAD_CAM mirror site :
http://206.19.206.56/emc.htm
The last item on this page is the patch you need, with the mod for saving
floating point status.

A bunch of people would love this!

I think you can run on 15MB (save 1 for the shared mem region).
I wouldn't even try for 8, that leaves way too little free.
I often have a couple extra sessions going, so I can edit tool path
programs, or just check a directory. I think 16 MB might be a little
tight, but I did do some early testing with EMC in 16 MB, and it does
work.
