Why won't Intel fix the Bad Axe 2 C1E/EIST problem???

I noticed that even after disabling C1E and EIST in the BIOS the CPU still uses it. The only way I've found to make it go away is to use RMClock. I've looked around the net and it seems like this has been a problem with these boards since they came out. It seems like by now Intel would have done something about it.
I couldn't figure out why my CPU kept throttling down even though I had both C1E and Speedstep disabled in the BIOS. Another user on this board mentioned RMClock and after running it I could see that C1E and EIST were both still running. I noticed that using RMClock to turn off C1E stops the throttling even though EIST is still running. I don't know all the ins and outs of C1E and EIST but I understand that they are similar although they function slightly different. Apparently having just EIST running doesn't cause throttling.
With that said, I did some benchmarks using Everest and found that there is no performance loss with C1E running. I suppose that with a very high overclock and super-duper voltages C1E might become a problem, but I haven't seen any so far. However, it seems that Intel would have done something about this by now. Surely someone has let them know about it.
I suppose this is a problem with all 975XBX2 boards and not just a few. The fact that I only found one post here and a couple others around the net about it makes me think that perhaps it might be a bug that only affects some Bad Axe 2 boards? I don't know, you tell me. If you're an owner of a 975XBX2, do you expereince this C1E problem?
