jump at boot

I've noticed a strange behaviour from Etrax when fiddling with early 
stages of boot process. If I try insert code in front of the kernel 
(compressed/head.S) the JUMP instruction krash my system. Sure odd! Bcc 
is OK though. Is there any magic initialisation I've missed? B.t.w it 
seems layout dependant, if I insert a bunch of NOP here and there it'll 
*sometimes* work...
