SeeedStudio BeagleBone Green (BBG) is clone of the BeagleBone Black (BBB) minus
the HDMI port and addition of two Grove connectors (i2c2 and usart2).
This board can be identified by the 1A value after A335BNLT (BBB) in the at24 eeprom:

Would still work when https://patchwork.kernel.org/patch/6394821/ gets in?

That will still work, but we need to extend the board identification
to "board-name" + "board-revision", as the Green choose the "A335BNLT"
board name in the eeprom to remain compatible with older 3.8.x images
from last year.. (most of the clones i've talked too want to support
the old image too)...
So with the 1st byte of the board-revision:
All BeagleBone Black's have: 0x30
Seeed's using 0x1A (with the potential to increment the A)
