Its not that easy... this will break the networking code locking, which is 
based on interupt priority.

You'll have also to change splnet() to spl6() (instead of spl3()) in
sys/arch/amiga/include/psl.h

And I suspect, that you'll have to change the amiga_ttyspl initialization in
machdep.c from PSL_S|PSL_IPL4 to PSL_S|PSL_IPL6... I seem to recall that there
was some ordering restriction between splnet and spltty.
