at the risk of annoying everyone with yet another post...

I'm interested to compare the amounts of space used by the two filesystems (original jffs2 versus cloned ext2):

Nokia-N800-50-2:~# df -k
Filesystem 1k-blocks Used Available Use% Mounted on

original:
/dev/mtdblock4 257536 176744 80792 69% /

cloned:
/dev/mmcblk1p2 507748 281846 199688 59% /

so jffs2 is giving me on average a 1.6 compression factor, meaning my original free space of 79MB might have given me around 126MB of usable app space.

So my double sized (1/2 GB) ext2 partition is only giving me an extra 116MB of space. Interesting.

I'll shut up now.
