let's try:
before reset:
alternating between 8+5 and 6+7, seems like every 500ms.
during reset:
8+7+5+3+2
8+7+3+2
IRQ+8+2+1
IRQ+1
(8 or IRQ)+5+4+1
OFF
(8 or IRQ)+5
(8 or IRQ)+5+3+2+1
3+2+1
5+4+3+2+1
ALL
ALL-1
KITT (until powerdown)

Legend: (8 or IRQ) means, i couldnt determine wether it is LED 8 or  
LED IRQ.  But always the same is lit.  KITT is like Knight Riders Car  
swinging from left to right and back.  Correlation is a bit difficult,  
but I think only the first two or threee states occur before the  
kernel returns the reset rejected.  So it looks like the kernel  
doesn't wait for the board to reset...
