Fixed the `slow printing' bug that occured with debugged kernels on RiscPC's. 

When the IOMD isnt mapped and all is mapped 1:1 a read gives garbage and thus
the obscure feature that slows down printing (or halts it!) when the mouse
button is pressed during output to the vidcconsole gets allways activated.

Included a simple flag that signals if the IOMD is mapped; the delay routine
won't check the mouse if this flag is still clear.
