I have tried it in both ports on the GX, but with the same results... No joy.
So what do you all recommend me to do?

Totally out of left field suggestion: Since this card seems to be quite rare, sell it to a collector and get 2 normal 128KB cards that behave normally. Sorry, not a technically savvy suggestion, but it may get you to where you want to be faster than continuing to fight with old/undocumented equipment.

One last thing - have you checked that card in a different GX and/or checked a different (e.g. 32 or 128KB) card in this machine to verify your machine is working properly.

Oh, yes I have tried different 128 KB Cards in the GX. These work just fine in the SX as well
