  21     This driver should provide support for most Aztech AZT2320 based cards.
  22     Several AZT2316 chips are also supported/tested, but autoprobe doesn't
  23     work: all module option have to be set.
  24
  25     No docs available for us at Aztech headquarters !!!   Unbelievable ...
  26     No other help obtained.
