This is rather strange. You're using an MX chip but it identifies itself as PMC. Is the RDID byteorder messed up?
I'm pretty sure the byteorder is OK. Even if the byteorder was messed up, a Macronix chip should have 0xC2 in there somewhere.
Three possible explanations: - the switch does not work as intended - the chip has been relabeled - we are reading garbage from the SuperIO.
