Qi - how do I make it boot from another partition on the SD card?

As I understand it Qi does this:
1: try to boot from 1st SD card partition
2: try to boot from 2nd SD card partition
3. try to boot from 3rd SD card partition
4. try to boot from NAND (aka built-in flash)

My SD card partition layout looks like this
p1 - vfat data partition (only data, nothing else)
p2 - ext3 primary partition, this is my main os. Currently holds QtMoko v8)
p3 - this is aother ext3 primary partition, for me to keep a backup os on.
Currently, it holds a copy of QtMoko v8.
p4 - swap, 128Megs


But - when I put a noboot-GTA02 file in /boot  on p2, Qi just stops. It
doesn't boot anything, not even the NAND.
I have to boot from NOR U-boot, select NAND and from there I mount p2 and
remove the noboot file.
(BTW, my NAND contains an old Om2008 image.)
