Right. git is hard at work as we speak :) I'm going to go for
DENX-v2.6.32.3 unless you say otherwise...

I've included this info as an attachment - hope that's ok. You'll see
that I've issued 2 commands: 'load_xenomai' and 'xenomai', both created
by me.

The other pair of commands you'll see in printenv, 'load_normal' and
'normal', work fine btw.

Cool. Thanks for the help!
