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
