Yes, of course it is possible to solve this problem otherwise.

In a sane hardware design you can read  this  information  from  some
board configuration register or so; for example, on the ADS5121 there
could  be  such  a  register implemented in the CPLD. But alas, there
ain't none.

Martha Marx posted pretty good patches (identifyung  board  revisions
based  on  the MAC address) more than a month ago, but then failed to
address the last review comments.

If you want to get that fixed, please pick up her patches  (or  nudge
her to do it for you).

Best regards,

Wolfgang Denk
