iomdkbc —
ARM IOMD keyboard and mouse ports
iomdkbc* at iomd?
pckbd* at iomdkbc?
pms* at iomdkbc?
The iomdkbc driver interfaces machine-independent
  drivers for PC keyboards and PS/2 mice to the particular implementation of the
  keyboard and mouse ports provided by the ARM IOMD20, ARM7500, and ARM7500FE.
  The quadrature mouse interface on the IOMD20 is handled by the
  acorn32/qms(4) driver.
This driver replaces the
    kbd(4) and
    rpckbd(4) drivers, which
    will be withdrawn in a future NetBSD release. If a
    kernel has kbd(4) or
    rpckbd(4) configured,
    iomdkbc will only be used for the mouse interface
    (if present).
The iomdkbc driver was introduced in
  NetBSD 2.0.
