Good. I suspect the eeprom write enable pin is electrically enabled on
the board by default. A bad idea in my opinion. If the eeprom gets
trashed then this kind of thing happens.
Byte[0] needs one if it's bits flipped from 0 to 1 to enable the MPEG
device. The audio tool below does that for a different bit. Off the top
of my head I don't remember which bit needs flipped. Trent may be
willing to help.

Your guess was right on the money. One of the users at the HD3000
posted a executable that looks at the HD3000's eeprom to enable the
onboard audio (rather then use the external jack). Running that
utility revealed that the onboard mpeg port is turned off:
josh@surprise:~/Desktop$ sudo ./i2c_detect

Are you sure you want to do this and write your card's EEPROM?
Type "yes" to continue:
I tried enabling the Audio Port (it is enabled now) and that worked
fine. Unfortunitly the script doesn't enable other options right now.
I am hoping that he can come up with a new binary (or post the code
for the executable) to fix it.

I don't understand why the pci sub device registers as 7060:3000 (which
comes from the eeprom) but you can't find the eeprom. If the eeprom is
dead I expected the PCI device list to show something like 14f1:8800
subdev 0000:0000.
Can you try the board under windows? Maybe some other driver bug is
preventing i2c access to the eeprom or the i2c bus.
Or, try the board with the native current ubuntu kernel (without the
latest v4l-dvb tree).

This isn't the right eeprom.
You should expect to see 7060:3000 somewhere in the first 8 bytes. Eg.
60 70 00 30
Try modprobing cx8800 with i2c_scan = 1
See if the eeprom is found at address 0xa0 or 0x50;
If it's not found, then that would explain everything.
