Both the factory layout and OpenWrt's changed a few times - the later just
to accommodate bigger kernels. Some factory firmwares did include a kernel
update, too.
I would suggest staying with the OpenWrt layour (maybe increase again the
size of the kernel partition):
- the bootloader loads the kernel from JFFS2
- most of the partitions in the factory firmware are empty
- the factory layout gives you almost no space to play with
But this is up to you now :)
Best,
Imre
