dual partition support does work, the cam boots from partition 1, then switches to partition 2.
All files from then on are accessed and saved from/to partition 2.
This means you need the CHDK files and folders in partition 2 to be able to run scripts etc.
Just copy the complete installation from partition 1 into partition 2.
Do not remove them from partition 1 or the cam will not startup.
