 	I looked through the kernel patch for the pcHDTV card, and as near as I 
can tell, the initialization and operation of the OREN chip has been 
obfuscated in i2c data packets:

char tu250266c[] = {
   0x00, 0xf8, 0x38, 0x6c, 0x00, 0x80, 0x39, 0x00, 0xf1, 0xff, 0x7f, 0x80, 0x00, 
0x20, 0x21, 0x7f,
   0x00, 0x20, 0x26, 0x7f, 0x72, 0x00, 0x00, 0x80, 0xf1, 0x70, 0x02, 0x69, 0x00, 
0x20, 0x96, 0x78,
   0x81, 0x90, 0x01, 0x69, 0x00, 0x20, 0x46, 0x7a, 0x11, 0x24, 0x00, 0x61, 0x00, 
0xd0, 0x01, 0x6c,

char tu250266d1[] = {
   0x5a, 0x5a, 0x5a, 0x5a, 0xe0, 0xff, 0x00, 0x00, 0x00, 0x00, 0x20, 0x00, 0xc0, 
0xff, 0x20, 0x00,

char tu250266d2[] = {
   0x00, 0x00, 0x00, 0x00, 0xe0, 0xff, 0x40, 0x00, 0xc0, 0xff, 0xc0, 0xff, 0x20, 
0x00, 0xe0, 0xff,
   0xe0, 0xff, 0xe0, 0xff, 0x40, 0x00, 0xe0, 0xff, 0x20, 0x00, 0x40, 0x00, 0x00, 
0x00, 0x00, 0x00,

and such.  No luck finding the magic code like:
