It is reasonable to expect that software for an accelerator would disable the 68882 on the logic board. That particular 68882 is located just where the accelerator software could expect to find it. 68882s on ethernet cards and adapter boards are trickier to find, so make it easier for the software by pulling the chip. I hate saying it, but for a soldered on chip, you might need to cut it out. But if it is on the logic board, leave it alone.
