Ok, I suppose I will have time to try it

All SD cards have wear leveling? Mine is a old 2Gb SD from my old Nokia N81.

You (or we) wanted to share the damage to each swap partition on SD card so when it changes from backup swap to another, it doesn't use always the same partition, uses RANDOM to equally distribute the use. If, as said by Estel wear leveling is implemented, then it's not needed at all.

Great!

Great solution... ops, more work to do XDDD. The time to wait might be big, to move the less possible data. We don't have "at" command in N900, so maybe a cron could be created and autoremoved, because an "sleep" command would be lose if you reboot the phone.
