the MTRR Base/Mask registers. If you use the documented algorithm in the systems programming guide, you'll get a GPF. The only thing that has prevented this so far is that the bios pre-sets some MTRR entries which we mis-interpreted sufficiently to fool the memcontrol interface into thinking all the address space was taken and therefore rejected XFree86's requests. However, not all bioses do this.. You get an insta-panic in that case. Grrr. A better fix (dynamic mask) will happen by 5.3/5-stable so that we automatically adapt to more than 40 physical bits.
