Good - the change worked and your card load correctly.

No that's not a problem.
I don't know what the encoding means though:

Obviously the "ab 12 18 07" at offset 01 is just a copy of PCI Subsystem
Vendor ID and Product ID for the MPC718 (12ab:0718).
There's a minor difference for the two cards EEPROMs at offset
0x14-0x15, which may be either part of a revision or serial number.
As more users with these boards report what they have, maybe I can
figure out what some of the other bytes mean.

Yup. I'm going to push a cleaned up set of changes for the cx18 driver
to dump out the eeprom for MPC718 boards.
Thanks for all the desoldering, photos, and testing. DVB-T for this
board wouldn't have been working without your efforts.
