Ok, I extracted the contents of your image, put them on partition 3, and after that I swapped partition number 1 and 3 in the partition table of my sd card while maintaining the start and end blocks. This way I was able to test meego without loosing data on the first (now third) partition.

And I think it looks very promising, and usable speed-wise (at least after I turned display compositing off).

Looking forward to what is coming.

EDIT:
just for the record, this is how I extract contents of raw images:

sudo kpartx meego-1.0-arm-n8x0-201005270252-sda.raw -a
sudo mount /dev/mapper/loop0p1 /mnt
sudo cp -raf /mnt/* /target_mount_point/
