Oops...  I forgot to verify the address of the demod chip...  Turns out
that the demodulator is at 20, not 0xa0...  So the correct data is:
bash-2.05b$ ./iic -f /dev/iic0 START 20 WRITE 1 0 STOP START 21 READ 5
05 02 09 20 01

And that does mean the tuner is the NXT2004, which is supported by
Linux...  guess I will be able to support it after reversing the
Linux code...
