Not quite on this topic, but still about bootloaders and the 2.3 image.

When I got ET9000, I flashed the new at the time bootloader 2011-07-19 (UBIFS).
If I understood it correctly, it was not really needed for the 2.2.1 image but was supposed to be needed with the new kernel later, with the new upcoming 2.3 image (and also to solve the image size limitations).
So can I load the 2.3 image with that bootloader or do I need the newest bootloader, the one that comes together with the 2.3 image?
