I was helping one of the guys on the IRC the other day to connect up a 
push button to the start I/O bit but don't know if he tested it or not...

I have just remembered that, as far as I am aware, this simply does not
work.

Has anyone ever made it work?

Should we just remove it? Or does someone want to try to fix it?

I spent about 10 days playing with it a year or so back, never got it to 
work like the docs say, failed miserably IOW. I'd like to see it work if 
somebody wants to drag it, kicking and screaming out of the '90's.

Making it Just Work would be quite a feather in LinuxCNC's hat.
