Jocke,

You still haven't reported weather the 4 nop's helped or not, yet you seek my help. I am just going to ignore you until you do test it.
finally I got both some time and hardware :
4 nops after _start does the trick, i.e. the board is up and running fine.
Diffing both System.maps and U-Boot hexdump gives only trivial results :
- "in_flash" and "_start_of_vectors" adress increment = 0x10.
- offset calculation for relative branch instruction also increases by 0x10.
Let me know if you need more information or something else tested.
I am not looking at this as I am busy but I have an idea or two
- CPU bug in 83xx CPUs which uses 0x110 as cold start vector.
- Misconfig of HRCW, don't know if you can change the reset vector that way but I guess you need to check.
I think a Freescale guy needs to look at this unless you can find something wrong with HRCW
