Wow, a lot of progress since I last came here.
Great work dj_steve!
I'm eager to try this, do you mind sharing the kernel patches, I'm using custom modules so I doubt the zImage is enough, plus I need to apply some other patches to it.

Thanks in advance

E: @ Dany-69, the kernel is on its own partition, type cat /proc/mtd to find out which one. I'd suggest not playing with any of the /dev/mtd* partitions (manually / without using flasher), you may screw up your device, permanently.
Anyways, kernel flashing is safe.
