OTOH, only the data in the 6-bit address space is really relevant in this 
case. So how does an 8-bit EEPROM reacts when it's addressed as a 6 bit 
one ?

cards to require bigger EEPROMs ?

Yup, but I was talking about the "else" branch of this "if" where the 
distinction is made again between 6 and 8 bit.

905C seems to fall in the second category (cf. docs).
