The Auto Switch stuff works by patching into int 0x10 and catching the 
mode changes requested, and then setting the correct mode registers.
Since Unix... doesn't have anything remotely like "int 0x10" there isn't
anything for the programmer to hook into.  You would really want to
implement this as ioctl()s to the driver  [ ioctl( egafd, ptr, IOHIRESEGA ); ]
or some such idea.
