It might. At the "base level", there is no difference between the 8xx and 9xx chipsets. What matters (going from memory here...) is the power that the board can deliver to the CPU. Assuming that its an advanced enough board, there is no reason why an 8xx series chipset can't support BD. Some do with the correct bios. If you have an older bios, you'll need to have a supported CPU first to flash it. I haven't heard of any 7xx chipsets/boards being able to support BD, though as you've found out they can support the x6 chips. Considering the issue with BD this isn't really a problem.
