yes, you're right. The "large" kernel will use 724848 bytes, and
the start address of the struct "fil" varies from 621736 to 622376.
The distribution stripped kernel reaches 526144.
My kernel wants 668580, still too much.
I put a printf in bootas code to know this. (start addr of the struct "fil")

Whe have to wait for it, then :)
