You mean "manually" controlling EEPROM clock and data lines, using
a different register?
A speed issue by chance?

If they have a different way to write to the EEPROM (using direct
access to EEPROM signals), then perhaps there is no EEPROM write mode
using VPD? VPD write mode (not writing to the address/F register, but
writing to VPD "storage" itself) is quite simple and permanent, thus
kind of dangerous. If it's R/O, then it can't erase the EEPROM (parts).

I see.

I wouldn't drop this patch permanently, though.
