Figured out where the prom console routines are on KA60 and how to invoke
them, thanks to old ultrix bootblocks lying around.
Also, enable M-Bus clock on the I/O slot IOCSR, this unstucks the cpu
clocks (which really are implemented on the SSC on the I/O module, but
need to be controlled via the cpu's ``internal'' processor registers...)
