Marc,

Good reasoning, but as it happens, this error message is not quite
unique.  The ivtv/tveeprom modules will additionally gripe about "not a
Hauppauge EEPROM".  The ivtv/tveeprom modules will usually return -121
corresponding to -EREMOTEIO.

Emilio,

This card is handled by the saa7134, module, not the ivtv module, so
newi2c doesn't apply.

"Huh, no eeprom present" in this case is being emitted by the saa7134
module itself and not the tveeprom module that ivtv uses.

"err=-5" is -EIO, referring to an I2C bus error with the i2c bus of the
saa7133.

With the saa7134 module "/sbin/modinfo" has two interesting options:
i2c_scan and i2c_debug which you may wish to try.

Regards,
Andy
