You can probably change it in /uevent.boardname.d - substitute in the board that you see. If you see uevent.goldfish.d, you can ignore that one. (It's for the emulator.) Let me know if it works for you.
This file is located on the initrd on the boot image, however, so you have to pull the boot image, split it, extract the initrd, change the uevent file, repack it, and flash it.

I've done that, and it sticks on boot now.
