So, ls triggers a real alignment problem which is now, due to the
fallthrouth to case 26, handled by the paging code...

As a temporary solution, i just copies the busybox from the installation
disk (which does not suffer from the same problem) and linked it to ls,
tar and sleep (being the userspace tools that trapped for me) which
allowed me to get a mostly working system up and running...

Now going to fix the real problem, on how to decide in the case 18 handler
if the trap is caused by a page fault or an alignment fault.

Cheers,
Jochen
