 * The current probe code works as follows
 * A) If the card uses a Bt878/879:
 *   1) Read the sub-system vendor id from the configuration EEPROM.
 *      Select the required tuner, audio mux arrangement and any other
 *      onboard features. If this fails, move to step B.
 * B) If it card uses a Bt848, 848A, 849A or an unknown Bt878/879:
 *   1) Look for I2C devices. If there are none fitted, it is an Intel or
 *      VideoLogic cards.
 *   2) Look for a configuration EEPROM.
 *   2a) If there is one at I2C address 0xa0 it may be
 *       a Hauppauge or an Osprey. Check the EEPROM contents to determine which
 *       one it is. For Hauppauge, select the tuner type and audio hardware.
 *   2b) If there is an EEPROM at I2C address 0xa8 it will be an STB card.
 *       We still have to guess on the tuner type.
 *              
 * C) If we do not know the card type from (A) or (B), guess at the tuner
 *    type based on the I2C address of the tuner.
 *
 * D) After determining the Tuner Type, we probe the i2c bus for other
 *    devices at known locations, eg IR-Remote Control, MSP34xx and TDA
 *    stereo chips.
