Thanks for the pointers, though what I ended up needing was: 

SHUTDOWNCMD "/sbin/shutdown -P -h now ; sudo -u noel qdbus
org.kde.ksmserver /KSMServer logout 0 2 2" 

shutdown was always executed previously, but was never able to force X
to exit, sitting there for 5/6 minutes before X eventually exited, then
shutting down, 

with the UPS only providing about 2 or so minutes power after
lowbatt-shutdown issue, this only caused FS corruptions, 

I kept shutdown first since desktop might not always be in X 

'sudo as user' was needed,  'nut' running as root rightly got qdbus
connect errors, since root was not running X :)

0 1 2 just reboots, but 0 2 2 halts. 

After 3 days system is fully powered off now after about 40 seconds. I
dont want to kill the battery too fast given the number if times its
been onbatt and exhausted in past few weeks, so will see how it goes
after a few weeks of uptime.
