The 8.11 drivers don't suffer from this problem, so I'd imagine it's just a temporary glitch until 9.1 and the equivalent W7 version come along any time now.
Temporary fixes are to either physically remove some RAM or to limit the available RAM via msconfig (I remember seeing that 3072mb works, apparently - no idea on more than that), which may be the best option if you're dual-booting.
Looks to be an incompatibility between the 8.12 drivers and recent Intel northbridges containing the memory controller.
