I am reconsidering the worth of working on this project.  This has not 
been much of a positive response.  In fact most of the response has been 
only bitching from people who want everything but are willing to 
contribute nothing.  Not having worked on this for years I had forgot 
how thankless this work is.

I may consider releasing it only if enough people are willing to donate 
to make this thankless grief worthwhile.

I have since discovered the actual minimum requirements for 32bit EL6. 
i686 minimum, and the kernel requires PAE hardware.  Some discussion 
seems to suggest it is reasonably easy to rebuild the EL6 kernel without 

i686 is considered to be:

* "Pentium Pro or later"
* "AMD K6 (but not all) or later"
* "Via C7" or later
* Geode LX, but not Geode GX

So minimal effort would support only more recent LTSP clients, which I 
guess would be the minority of deployed hardware.
