EEPROM checksumming should always work and if the card's EEPROM checksum
does not check out the card is likely busted. The software work arounds
to add support for a card with busted EEPROM are just too much if a pain
in the ass to deal with, it would introduce a lot of complexity. In the
best case scenerio a sample EEPROM would need to be provided for each
type of EEPROM supported (or a few) with some default values which we
can gaurantee work well for the card. Note that the cards's EEPROM even
contains calibrate data, and antenna information, so this makes this
really difficult to do, and I would simply advise against it.
