I found some OpenBSD docs about loadbds, there it sais, -S is default on. But
there is some option to disable Symbols loading. On the other hand, i tried
to load it into chipmem with -Z or so, the numbers are even more confusing, but
the result is the same. So i assume the kernel really gets started and simply
crashes for some reason.

Maybe the only chance is to set up my A2000 and look into the kernel sources,
and set some debug traps, like i do on VAXen. (Have to use the parallel port
instead of the LEDs on VAXstations :-)

Ok, this seems ok. But currently, i don't think of a problem with some memory
stuff. The kernel simply doesn't seem to work on my A1200. Is there anybody
out there using NetBSD on an A1200?
