restore
dd of=/dev/your_ps3_hdd if=/mnt/hdd_big_enough/ps3_save
you can also use some compression ... e.g.
dd if=/dev/your_ps3_hdd | gzip -9 > /mnt/hdd_big_enough/ps3_save.gz
opposite way is
gunzip -c /mnt/hdd_big_enough/ps3_save.gz | dd of=/dev/your_ps3_hdd

This is the method I used, but it is only useful if you're restoring to the same size hdd. Also, I recommend adding in a bs=10M as it will speed things up considerably:
dd bs=10M if=/dev/your_ps3_hdd | gzip -9 > /mnt/hdd_big_enough/ps3_save.gz

It's not very effective, but it has some effect, especially on large drives. I was able to reduce my 500GB drive down to a 321GB gzip'd file.

I think from kboot you could use dd to make an image of the Linux partition (save it onto a USB drive) and then after upgrading to a larger HDD, use dd again to restore it back.
If you can't do it from kboot, then I'd try from single user mode without the Linux partition mounted.
