I've noticed that the address locations for the 1D maps are also in the ROM in 4-byte chunks like the 3d/2d references (for example, "0x000C0440". I've seen them in the 0x14xxx range, and every 1D map location I've tried is found in the ROM. I can't make out any pattern to the data in-between, so I'm assuming that this area is all "programming logic". Don't know if this useful or not for finding tables, but I was able to find a few 1D tables I needed in an unknown revision by finding similar "in-between" data from a known ROM and then tracking down the address on the unknown ROM.
