That's almost the way I do ...
I have 3 partitions too but 1. ist production system
2. is log partition
3. is backup partition which I do an upgrade from the first partition

Then I reboot to this partition with lilo
  lilo -R <ImageName>
  reboot
(of course this image but be a valid entry on the first partition in
lilo.conf)

I everything works you can activate the second one as default or upgrade
first partition.
If something goes wrong power on/off and you have your good old system
back...
