Looking for Pali's newer version (not found yet ), I noticed that with sd swap activated the ext4 partition moves from mmc1 to mmc1p1 also without usb connection giving a stability issue.

I've found this guide for ext2, but i haven't yet tried it: http://wiki.maemo.org/Ext2_on_microSD_card
Maybe it can be the solution for our issue and a good improvement for next CSSU.
