Ok, here's the problem.  Yeah, please do not submit profiles that
require a card= specification.  Instead, please resubmit your patch
including an entry in the em28xx_i2c_hash[] table that includes your
device.  It probably needs to look something like the following:

{0x6ba50080, EM2820_BOARD_PLEXTOR_PX_AV200U, TUNER_LG_PAL_NEW_TAPC},

I am curious though why your eeprom hash is blank even though it
successfully dumped out the eeprom.
