There is a new experiment RTAI kernel available, developed by Paolo, 
Shabby, and memleak.  I've been running it on some of my machines (it's 
been working well), and it's running one of the buildslaves in the buildbot.

It's a 32-bit kernel with PAE support, suitable for running any X86 
processor with up to 4 GB of physical memory.

The kernel is available here:

http://www.highlab.com/~seb/linuxcnc/rtai-for-3.4-prerelease/

I would love to have other folks test it and report how it works for them.

The install procedure is:

* Make a fresh install of Ubuntu Precise 12.04, 32-bit.  Any flavor 
should work.

* Download the files from the URL above.

* Install (with "dpkg -i") linux-image and rtai-modules.  The other debs 
are optional.

* We don't yet provide debs for Precise RTAI, so you'll have to build 
linuxcnc from source.  Both the 2.5 branch and master are known to work 
with RTAI on Precise.
