I know what you mean, when i was 1st looking to migrate i couldnt understand any of it...
when i finally did , i followed this guide http://www.kurobox.com/mwiki/index.php/Kurobox_support_in_stock_2.6_kernels
It was simple to follow and i didnt have any problems.
The only issues for me were the post uboot changes, for example , ttyS0 and ttyS1 have swapped round and the AVR Watchdog needs attention (if you start rebooting every 5 mins or so, then look at the AVR scripts)
I would just give it a go
Note: if you get to the pre flash check (boot from ram i think) and it doesnt work then stop cus you have not erased anything yet.
