# pc_keyb.c:
#   Fix: Disable interrupts during keyboard initialization.
#      The initialization does cause keyboard interrupts. On most platforms this
#      should not be a problem. But if there is no interrupt controller the
#      interrupt might retriggered for ever. This happended on the m68k/TekXpress
#      port.
