Answers from the master himself. Great!

  1. unpacked the contents of the 2007HE fiasco image using Nokias flasher tool
  2. mounted rootfs.jffs2 to some directory (all the block2mtd / losetup...-magic applies)
  3. copied everything from there to MMC

This is the most important information. Thank you!
Not knowing if rootfs.jffs2 would be enough or if somehow contents from initfs.jffs2 are required (like for additional kernel modules etc.) left me in empty space with too many possible combinations for trial and error.

Logical consequence... so, how about OS2007HE and OS2006, then? IIRC, in recent HE, the kernel is basically the same as in OS2006, but they did apply changes to the initfs? Could this be the reason it doesn't work? Or is it known that OS2007HE can dual-boot from MMC on a system that uses a OS2006-initfs?
