That’s excellent, and most helpful.  So that brings support for newer
hardware, AND provides a PAE version which works on all my hardware 
nicely.

This might be useful to a number of people, and it was only through looking
around CentOS 7 on Raspberry Pi that I happened across the kernel repo.  
Might it be worth linking to the repo from the AltArch/i386 page:

Yep - wise words and duly noted, thank you.  My application is small scale,
so should be fine.  Software is only as good as the testing anyway :-)

Last question, if I may - Is there any specific reason why an i686 PAE kernel 
built from the main RHEL sources isn't in the AltArch i386 os- repo?  

Notably CentOS 6 provided both non-PAE and PAE 32-bit kernels, and it's 
that step from CentOS 6 32-bit PAE onto CentOS 7 32-bit which made me 
stumble, but okay now.

Many Thanks again,

Mike
