Two other useful links, http://schmots.blogspot.com/, read the 2nd section "dual boot" onward. Another one, http://examplified.net/guide/Nokia_7...ting_from_MMC/, it is for 770, so do not follow verbatum, just an exercise for you to get familiar with.
1) set up a boot menu, http://fanoush.wz.cz/maemo/#initfs



2) Gather the two programs, wget and e2fsprogs, which you already did.
3) Partition the card using sfdisk; if not sure, post it and I will help you.
4) Format only the mkdosfs /dev/mmcblk0p1
5) follow this thread #1 step by step,
