i got the 2.5G copper sfps, and tried them...they work well with the v12 (including this patch), but not in v13...
i dumped the eeprom like you mention for your database:
$ hexdump -C 2g5_sfp.bin

i guess this sfp have a phy as it can operate in 100/1000/2500 mode like described on the module.
but only tested in 2500base-T mode only.
